Nowadays Thai farmers confront with the slowdown of rice price problems and the more increasing price of materials. Thus, the expense exceeds the revenue and the farmers do not have enough money. Because paddy rice that farmers sold are contain of more moisture more than 15%, thus the quality of paddy rice is not good. Therefore, the price is cheap based on the quality of paddy rice. Moreover, the consumer demands of rice are steady throughout the year but the rice products are sold by the farmer only after the harvest period. As a result, the price decreased during that period. The merchants/middlemen usually stock rice and resell again afterwards. The paddy silo is the concept for bulk storage of paddy; silo can control storage conditions which will constantly maintain the quality of paddy and prevent access by the rodents, birds and insects. After keep the paddy in silo for the period, the paddy will be sold to the market again at the suitable period. In addition, the qualities of paddy products are not change and the moisture in the paddy will meet the standard.

Post Harvest Loss

The aim of this write up is to explore technological developments in the area of post-harvest grain storage techniques. Post-harvest losses occur between harvest and the moment of human consumption. They include on-farm losses, such as when grain is threshed, winnowed, and dried, as well as losses along the chain during transportation, storage, and processing. Use of traditional grain storage facilities such as cribs, improved rhombus, and brick bins are ineffective against mold and insects already present in the grain before storage. While plastic bins reduce insect pests’ infestation, Purdue Improved crop storage bags and wooden silo were proved to be a viable management tool for preventing aflatoxin accumulation in storage and moisture migration. The metal silo still remains an effective grain storage technology for reducing post-harvest insect and pathogen losses if the challenges of moisture and temperature can be adequately managed. An effective grain storage technology would be the ones that can sustain quality of grain stored for a long period (≥5 years), durable, cost-effective, and be managed scientifically, possibly by computer-aided grain management system.

And Storage

The problem of grain storage and storage can be approached from two perspectives: storage and storage of cereals and technical plants within individual agricultural holdings; storage and storage of cereals and technical plants within agricultural associations and companies. At the level of Romania, the storage and storage of cereals at small agricultural producers are deficient in terms of ensuring optimal storage conditions according to standards. These variants include: preservation at low temperatures; preservation by active aeration; self-preservation; chemical preservation; conservation with the help of radiation. In the paper we will approach the conservation by active aeration because it folds better for small agricultural producers. Proper aeration is one of the most important processes in a grain storage system and is essential for maintaining the quality of stored products. Aeration means the movement of a relatively small volume of air through the grain mass in order to control the temperature of the grain and to reduce the risk of product degradation. The two main objectives of aeration are to maintain a uniform temperature in the grain mass and at the same time the temperature must be as low as possible from a practical point of view. The paper will present the results of experiments for storing bulk grain in a metal cell with central aeration system, which is based on a patent. This type of storage system can be used successfully in small agricultural producers.

In enterprises with limited capacities and a low-powered grain drying facilities there is a problem of economical and reliable storage of dry, wet and moist grains. One of the options for its successful solution is the application of grain storage technology in silo bags, tested in many enterprises, the basic principle of which is based on the self-preservation of grain under hermetic conditions in an environment of carbon dioxide. To implement this technology, it is necessary to determine the suitability of the batch of grain for loading in the silo bags on the basis of an operational analysis of the grain quality. After loading the grain, the silo bags are sealed, the grain mass is stored for a certain time and then unloaded. After many years of industrial testing of grain storage technology in silobags, recommendations have been developed that allow to ensure the quantity and proper quality of grain in the process of implementation of the technology. To do this, it is provided to carry out a whole range of activities - personnel training, the selection and preparation of a storage area for grain, deratization, the determination of the quality of grain at all stages and a safe shelf-life, depending on the condition of the grain, weighing of the grain; loading silo bags and placing them on the site; drawing of marks for identification of silobags; monitoring of the state of silo bags and grain and the restoration of the integrity of the silo bags throughout the storage period; accounting for grain in the silobags; processing of unconditioned grain; object protection, final analysis of the work performed, identify problems and ways to solve them. The storage site for grain in the silo bags must be cleaned of stubble and grass, sharp objects, grain residues, solid hardwood or the most densely packed soil (the clay surface is undesirable, as precipitation makes imposible laying and unloading of silobags), ensure no stagnation of water during rains and melting snow, provide the possibility of free movement of special equipment on the site. It must be deratized and fenced with a mesh with small openings, a height of at least 1 m and dipped. The analysis of the characteristics of three-layer silobags showed that to optimize the storage of dry grain, it is advisable to use the largest silobags of 90 m in length, since they have a larger capacity, there will be less time spent on dressing and sealing the silobags, saving space between the silo bags lying along one another , there will be less length of silobags to go for tying, as well as saving money on the cost of silobags, the cost of working time and fuel (decreases the number of transfers of special equipment). It is advisable to take into account the possibility of unloading the sleeve during one shift. At all stages (loading, storage, unloading) the determination of the quality of grain, monitoring the condition and restoring the integrity of the silo bags checking the sanitary condition of the site and the presence of baits should be carried out. Precautions should be observed, grain accounting, working with non-standard grain and final analysis of grain storage results should be carried out.

Abstract The quality of hops is significantly affected by the content of alpha bitter acids. Maintaining it with minimum losses lies within the competence of both the hop grower and processor depending on how they follow the optimum harvest technology, storage conditions, and post-harvest hop processing. That indicator is considerably affected by the hop storage method, i.e. whether the warehouse is air-conditioned or not, as well as the storage duration. The alpha bitter acid content should not be reduced during storage. The objective of this paper is an analysis of the alpha bitter acid content in the Saaz hop variety in a technological sequence of operations starting with drying at the grower and finishing with six-month storing at the processor, with three storage variants: an air-conditioned warehouse, non-conditioned warehouse, and a variant in which the square bale is moved after 60 days from a non-conditioned warehouse into an air-conditioned warehouse. The analysis of samples to identify the alpha bitter acid content was carried out by means of the ASBC Hops-6 and the HPLC EBC 7.7 methods. Practically in all cases the alpha content declines, although if a square bale is placed in an air-conditioned warehouse this decline is the lowest depending on the storage duration. The economic analysis shows a significant profit referring to the price of alpha contained in 1 t of hops stored in an air-conditioned warehouse. At the date of 1/11/2015 this profit was 14 706 CZK, at the date of 4/1/2016 it was 7646 CZK, and at 1/3/2016 the profit was 6587 CZK.

Abstract: India is a country with a booming population and limited resources. 40 % of food grains are being wasted annually out of the world’s production due to factors like improper post-harvest management, lack of storage spaces, storage facilities, handling and distribution of food grains, etc. Thus an effective solution is required to bridge the gap between surplus production and hunger. The objective of our project is to develop methods for retaining the quality of food grains under a controlled environment for effective storage and distribution. Automation using sensors helps to prevent illegal racketing with data collection, monitor storage conditions like temperature and humidity levels, and eliminate man-to-man contact. When dispensed, the level and quantity of the grains can also be recorded. Thus, this machine is better than the existing manual methods of distribution as it acknowledges fair distribution and quality preservation.

And Storage

The influence of storage conditions on the quality of tomato fruits was tested. The rate of ripening was established in normal air, where tomatoes ripen quickly, under controlled atmosphere where they ripen more slowly and under low pressure, where they ripen slowest. The influence of post-harvest benomyl or methylthiophanate treatment on tomato rot, ripening, and biological value were examined. Post-harvest tomato treatment did not reduce fruit rot. The color of fruits and the processed products depended on the fungicide treatment. Concentrated tomato pulp made of fruits treated with methylthiophanate was redder than the others. The fungicide treatment increased or decreased the level of some chemical substances in the fruits in dependence on the applied fungicide, storage conditions and the length of storage, e.g. tomatoes treated with benomyl and stored for 14 days contained the highest level of vitamin C under 0% CO<sub>2</sub>:3%O<sub>2</sub> and tomatoes treated with methylthiophanate contained the highest level of vitamin C under 38 mm Hg. Degradation of vitamin C in pulp was faster than in the concentrated pulp. Tomato pulp made of tomatoes treated with methylthiophanate contained the lowest level of vitamin C.
