Special automatic circulation dryer for drying preboiled rice

Abstract

The invention relates to a special automatic circulation dryer for drying preboiled rice. The dryer comprises a combined-type vibration cleaning screen, one end of the combined-type vibration cleaningscreen is provided, through a first elevator, with a first scraper machine which is connected to a first steel plate bin, a second steel plate bin and a third steel plate bin, the discharging gate plate valve at the bottom of the first steel plate bin, the second steel plate bin and the third steel plate bin is connected to a second scraper machine positioned above the water tank through a secondelevator, the top of a water tank is connected to a first soaking tank, a second soaking tank, a third soaking tank and a water pump respectively through conduits, one end, far from the vibration cleaning screen, of one side of the first soaking tank is connected to a third scraper machine positioned at the top of a cooking tank through a third elevator, the bottom of the cooking tank is connected to a fourth elevator through a discharging ball valve, and the top of the fourth elevator is connected to a fourth scraper machine positioned at the top of the dryer. The dryer has the beneficial effects that: the control effect is good, the heating, cooking and drying procedures of rice are effectively carried out, and the high quality of the product is ensured.

Description

technical field [0001] The invention relates to the technical field of agricultural grain drying equipment, in particular to a special automatic circulation dryer for drying parboiled rice. Background technique [0002] Dryers can be divided into industrial and civilian. Industrial dryers are also called drying equipment or dryers. Civilian dryers are one of washing machines. They are generally used to remove clothing and other textiles after washing and dehydration. of moisture. [0003] The dryer has several modes such as belt drying, drum drying, box drying, and tower drying; the heat source includes coal, electricity, gas, etc.; the drying process of materials has hot air flow type and radiation type, etc. , hot air drum drying is that the hot air flow moves forward from the tail, fully contacts with the material, and makes full use of the heat transfer through heat conduction, convection, and radiation; the heat energy is directly transferred to the material, so that t...

AI Technical Summary

Problems solved by technology

[0004] During the drying process, the rice needs to be soaked and steamed first, and the corresponding pressure and temperature need to be set for the soaking and steaming. After processing for a certain period of time, it is then heated and dried by a dryer. During the working process, the automatic circulation dryer for rice drying cannot effectively control the temperature, flow and pressure. When the grain is dried inside the dryer, the contact surface is not large enough, and the grain will be damaged. There are products with poor drying effect, which affects the later process and reduces the quality
