Physical Phenomena

The search for resource-saving and environmentally friendly technologies and technical solutions in the production of food products should occur through the development and development of new analytical methods and constructive measures, which will lead to progress in this field not only in our country but also abroad. The efficient use of processing facilities has always been characterized by its high level of mechanization. Drying is one of the most widespread technological operations in various industries of processing and food production, in particular in the preservation of raw materials. Prospects for the development of drying technologies include reducing energy costs for moisture extraction; improving the quality of dried products; development of highly efficient universal equipment; ensuring the environmental safety of drying plants. When studying different physical phenomena in the process of vibration drying, two methods of research are used, which allow to obtain quantitative regularities. In the first method is used experimental study of specific properties of a single phenomenon, in the second - based on a theoretical study of this problem. The advantage of the experimental research method is the reliability of the obtained results. The analysis of literature sources is carried out and the necessity and possibility of creation of new designs of dryers using infrared influence on the product and vibrational vibrations of the working container for intensification of the drying process is substantiated. The proposed design of an experimental laboratory drying unit for drying granular and granular materials in a vibrating boiling layer allows to identify patterns of changes in the parameters of the drying process, to obtain data to optimize the process and to develop a method of engineering calculation of devices for infrared drying.

Introduction. Rose hips are rich in macro- and micronutrients. Unfortunately, heat treatment destroys most nutrients. Ultrasonic technologies make it possible to reduce the drying time and lower the temperature regime. The research objective was to adjust ultrasound technology to rose hip production in order to reduce the loss of vitamins and improve the quality indicators of the dried product. Study objects and methods. The research featured rose hips of the Rosa canina species collected in the south of Kazakhstan. This subspecies of wild rose is poor in vitamin C. Nevertheless, this shrub is extremely common in Russia and other countries of the Commonwealth of Independent States. The raw material was dried according to standard methods. One group of samples was treated with ultrasound, while the other served as control. Both groups underwent a sensory evaluation and were tested for moisture and vitamin C. Results and discussion. The rose hips were dried in a combination steam oven with a built-in ultrasonic wave generator. The research revealed the following optimal parameters of the ultrasound drying process: frequency of ultrasonic vibrations – 22 kHz, processing time – 2.5 h, temperature in the combination steam oven – +56°C, initial moisture content – 30%. The resulting product met the requirements of State Standard. The loss of moisture was 57%. According to State Standard 1994-93, the initial moisture content should be 15% or less. Time decreased from 360 min to 160 min, and the initial moisture was 13%. The experiment confirmed the initial hypothesis that ultrasonic treatment improves the drying process by improving quality indicators and preserving vitamin C in raw materials using. Conclusion. Ultrasound treatment during moisture removal from rose hips provides a resource-saving technology that fulfills an economically and socially important function.

Biomass of microorganisms in aerogenic dissemination is an allergen and causes bronchopulmonary pathology. Organized source of air-gas emissions (AGE) in the production of protein—vitamin additives of any kind of raw materials are driers, bioreactors and separators. There were provided the results of a survey of a number of AGE production. There were developed new types of gas treatment equipment – vortex absorber and a mesh mist separator with continuous regeneration for bioreactors and separators. The greatest contribution to the AGE of fodder protein production make drying compartments. New technical solutions for their technological improvement did not on the path of increasing of gas treatment equipment capacity, but on the path to change hardware technological scheme. There were developed and tested a few schemes with varying degrees of closure of drying agent’s (DA) circulation. The final decision was the scheme with a fully closed-loop circulation of DA, thus ensuring the full environmental safety and explosion-proof of drying compartments.

One of the resource-saving methods of drying, from the point of view of preserving food and biological value, providing the appropriate recovery properties of dried food products (DFP) and energy intensity of the process, is drying with mixed heat supply (MHS drying). The scientific concept of work on the formation of a universal and DFP stable functional and technological potential is formulated, which is the basis for modeling and designing the formulation composition and technology of food products by groups and types with its use or interchangeability. As the subject of research for the formation of quality indicators of cereals, white cabbage is selected, as it is a typical vegetable for Ukraine and accordingly has a high degree of assimilation of natural micronutrients in the human body. Structural studies have shown the predominantly crystalline structure of polysaccharides, that is, less than their transformation under conditions of MHS drying, as compared with convective conditions. The effect of MHS drying on the formation of DFP quality indicators is determined by the method of recording IR spectra with Fourier transform. For studies of the violation of total internal reflection, it has been established that the process of DFP reduction leads to an increase in the availability of organic substances in the solvent, which will facilitate the extraction of extractives in the recovery of raw materials. It is established by the number of aroma, the more aromatic-forming substances are contained in the MHS drying samples irrespective of the process temperature, less in the dried samples of the convective method. This is due to the reduction of thermal and thermal effects during MHS drying, which slows down chemical transformations and removes aromatic substances. It is proved by the tensometric method, with the convective method due to shrinkage during dehydration, the changes during sorption and desorption are insignificant. When MHS drying, such changes are expressed: during the sorption of vapors, DFP is well restored, the capillaries swell, so the differential distribution function of the pores expands, the average radius of the capillaries increases 4 ... 6 times. The research results make it possible to form the functional and technological parameters of cabbage powder, to simulate the formulation of new food products with this ingredient and to optimize the production technology.

The article investigates the drying properties of ceramic mass in the system “loesslike loam - ash of Ekibastuz HPP”. Ceramdor obtained from pure loam was selected as a control sample. A change in the structural and mechanical characteristics of ceramic masses during the drying process is associated with a change in temperature and moisture content of the material. The following results were obtained: molding moisture indicators, ductility numbers decrease with increasing ash. According to the classification of clay raw materials by plasticity, loam from a moderately plastic state goes into the category of low-plastic raw materials. With an increase in ash content of up to 20%, the sensitivity coefficient to drying leads to an increase in the time of crack appearance on the samples. A slight decrease in strength indicators is observed from 5.4 to 4.5 MPa. Thus, the results serve as the basis for the development of technological parameters in order to obtain ceramdor.

We have developed a resource-saving, low-waste technology for the disposal of highly toxic phenol-containing wastewater that enables to utilize phenol and formaldehyde as an organic binder. The technology involves the use of technogenic raw materials («overresin» water from the production of phenol-formaldehyde resins, soft wood waste, waste from the production and processing of laminated plastics) and processes of regeneration, recovery and conversion of phenol. The optimal technological parameters of phenol sorption on wood sorbent and secondary poly/condensation were experimentally established. This in turn provides a high degree of neutralization and extraction of resin-forming components from wastewater and subsequent production wood-polymer thermoplastic structural composite and sodium phenolate on their basis.

The issues of ensuring the environmental safety of the functioning of the processing industry in the agro-industrial complex of Russia, on the basis of economic mechanisms, are considered. The high level of resource use in the processing of agricultural products contributes to environmental pollution, reduces the competitiveness of the industry, increases the level of costs. A rather large deterioration and obsolescence of the equipment of the processing enterprises of the agro-industrial complex does not allow for the environmentally safe processing of agricultural products. Of particular concern are enterprises of the meat processing industry, which produce waste, which creates an unfavorable sanitary and epidemiological situation in the regions. In this regard, it is necessary to develop such a system of economic incentives for the implementation of resource-saving projects of the processing industry enterprises in the agro-industrial complex, which would improve the environmental and economic efficiency of the studied industry. Given the high capital investment in modern resource-saving equipment, it is advisable to pay attention to the sources of funding for these projects on a preferential basis. Among the measures for the economic stimulation of projects for the processing of agricultural products by the industrial method, the article proposes both credit and financial instruments, including preferential loans and leasing, and preferential taxation, and an environmental fee. In order to stimulate projects for the acquisition of resource-saving equipment in the processing of agricultural products, it is proposed to use such an effective tool as accelerated depreciation, which allows manufacturers to reduce costs when replacing old equipment with more modern ones. In order to increase risk management efficiency, when implementing projects for industrial processing of agricultural products, it is proposed to use public-private partnership tools that minimize risks, including environmental ones, due to their redistribution between participants, based on such forms as delegation of management and concessions.

In Ukraine, along with the growing demand for tonnage production of light fillers, the need for raw materials is growing, considering that most of the range of light fillers is made from natural raw materials. Thus, a promising direction of utilization of TPP slags and coal concentrate obtained by enrichment of primary coal sludge is there involvement to the production process after preliminary drying. Drying of the thermal power plant slag and the coal concentrate, which are hydraulic mixtures, by the filtration method will reduce energy consumption due to the displacement and removal of significant amount of moisture by the moving thermal agent due to the pressure drop. The results of studies of the thermal agent velocity effect on the drying process duration of TPP slag and coal concentrate, as well as the obtained values of heat transfer coefficients at different velocities of the thermal agent for TPP slag α = 40 ÷ 112 and coal concentrate α = 92,5 ÷ 294 will allow to calculate energy consumption and scientifically substantiate the optimal technological parameters for intensification of the drying process of the charge components for porous fillers production.
