Drying process for green bean seeds

Abstract

The invention discloses a drying process for green bean seeds which dries green bean seeds by applying an enclosed steam compression heat pump drying equipment with an auxiliary condenser. The drying process for green bean seeds includes the following steps of inputting an initial moisture content and a target moisture content of the green beans; determining cycling times for drying according to values of the initial moisture content, the target moisture content and the differential value between the initial moisture content and the target moisture content; setting process conditions, such as moisture content, drying temperature, wind speed performance, continuous drying time and tempering drying time and the like; shutting down the compressor and entering into the tempering drying stage after the continuous drying stage, monitoring the moisture content of the green beans in real time through a seed sample weighing system inside a drying oven, adjusting the tempering drying time according to the differential value between the current green bean seed moisture content and the target moisture content, and stopping the tempering drying and ending the drying process of green beans when the seed moisture content reaches the target value. The drying process for green bean seeds has the advantages of environmental protection, low consumption, high degree of automation, wide scope of application and good drying quality.

Description

technical field [0001] The invention relates to a drying process for crop seeds, in particular to a drying process for green bean seeds. Background technique [0002] Green beans are leguminous plants, which can be divided into green-skinned yellow-kernel soybeans and green-skinned green-kernel soybeans. Green beans were first produced in China, and the planting areas are mainly distributed in Northeast China, North China, Shaanxi, Sichuan and the lower reaches of the Yangtze River. Green beans are rich in protein, edible sugars, dietary fiber, isoflavones and anti-cancer health ingredients. Compared with soybeans, green beans have the characteristics of high sugar and low fat. In addition to being used as seeds for agricultural production, green bean seeds can also be used as auxiliary materials for vegetables or other foods or as raw materials to produce soybean milk powder, snack foods, etc. The moisture content of timely harvested green bean seeds is higher than the saf...

Problems solved by technology

Although there are many types of dryers available to dry green bean seeds, considering the high germination rate of green beans as seeds, the difficulty of process control in the drying process, and the energy consumption of drying, an appropriate dryer must be used.
