While fulfilling the food demand of an increasing population remains a major global concern, more than one-third of food is lost or wasted in postharvest operations. Cereal grains are the basis of staple food in most of the developing nations, and account for the maximum postharvest losses on a calorific basis among all agricultural commodities. This paper provides a comprehensive literature review of the grain postharvest losses in developing countries, the status and causes of storage losses and discusses the technological interventions to reduce these losses. The basics of hermetic storage, various technology options, and their effectiveness on several crops in different localities are discussed in detail. Meeting the food demand of a rapidly increasing global population is emerging as a big challenge to mankind.

The drying of grains and oilseeds is critical for downstream processing and storage as it prevents caking, agglomeration, spoilage and degradation of material. Controllability of the drying process is important to compensate for changes in the feedstock. Excessive drying of grains and oilseeds is undesirable and results in weight loss, whereas too much moisture can lead to degradation and numerous quality issues during storage and penalties at sale. Varying weather and process conditions call for the need for more efficient and flexible methods of drying grains and oilseeds. Also, solids have different limits on temperatures that they can be heated up to and varying ideal moisture content for storage. Natural drying is not always an option and many variations of the air drying method have been used. The drying process is governed by typical factors like ambient conditions outside, relative humidity, temperature, grain texture, sensitivity to heat, moisture content and toughness of the grains.

Updated: December 5, An oilseed press may be the heart of an oilseed pressing operation, but the quality and cleanliness of the seed available for pressing plays a large part in the ability of the press to perform its job.

Drying and Storage Of Grains and Oilseeds

It seems that you're in Germany. We have a dedicated site for Germany. Authors: Brooker , Donald B. This text and reference discusses the drying of grains, in particular the staple cereals, maize, rice, and wheat, and the oilseeds, soybeans and canola. The basic physical and thermodynamic properties of grain and air are examined, and the theory of the drying process is developed. Design of the optimum operating conditions for on-farm and off-farm dryers are presented.

Bulk storage drying, sometimes called near ambient drying,uses either unheated air or air heated to no more than 5 o C above ambient temperature. Potentially it is a cheaper alternative than drying in heated-air batch or continuous-flow dryers but drying may take several days or weeks and needs careful control. The moisture content m. Given time and with adequate ventilation, the two will reach an equilibrium. Figure 1 shows the relationship between r.

Ultra-efficient technology for drying grains and oilseeds

Она поняла: все дело в деньгах. Она перенеслась мыслями в тот вечер, когда президент Джорджтаунского университета предложил Дэвиду повышение - должность декана факультета лингвистики. Президент объяснил, что преподавательских часов будет меньше, бумажной работы больше, - но гораздо выше будет и жалованье. Сьюзан хотелось закричать: Дэвид, не соглашайся. Это не принесет тебе радости.

 Какой тип? - Беккер хмуро взглянул на полицейского. - Тот, что вызвал скорую. Он болтал что-то на ужаснейшем испанском, который мне только доводилось слышать. - Он сказал, что на руке у мистера Танкадо было кольцо.

 Спасибо. Я лишь хотел спросить, есть ли в городе клубы, где собираются молодые люди - панки. - Клубы. Для панков? - переспросил бармен, странно посмотрев на Беккера. - Да.
