Air drying machine for pre-processing raw materials in rice oil preparation

Abstract

The invention relates to an air drying machine for pre-processing raw materials in rice oil preparation. The air drying machine is characterized by mainly comprising an air outlet drum, an air drying drum, vibrating devices and a screen. The top end of the air drying drum is connected with the air outlet drum, a feeding port is arranged at the edge of the air outlet drum, a discharging port and an upright air inlet are arranged at the bottom of the air drying drum, the screen is arranged in a drum body of the air drying drum, and two bilaterally symmetrical vibrating devices are arranged on an outer wall of the middle section of the air drying drum. The air drying machine is arranged behind a granulator, air dries rice bran grains, can reduce moisture content in the rice bran grains, can guarantee that rice oil in rice bran is not inactivated, can improve quality of finally obtained rice oil, and is simple and reasonable in structural design and easy to popularize and apply.

Description

technical field [0001] The invention relates to equipment in the process of preparing rice oil, in particular to an air dryer for raw material pretreatment in the preparation of rice oil. Background technique [0002] In the existing production process of rice oil, the pretreatment stage of rice bran is mostly relatively simple. The common pretreatment process of rice bran is to stir fry the rice bran in a frying pan for pre-water removal, and then the rice bran enters the granulator Granulation, transported to the storage box through the sealing rubber dragon, stored, and used for subsequent processes. At present, the water content of the raw materials obtained by this rice bran pretreatment process is as high as about 17%. If the water content is too high, it will directly affect the subsequent process of granulation, and the leaching workshop will consume a lot of solvents. . In addition, there are some small improvements to the pretreatment process of rice bran, such a...

Problems solved by technology

At present, the water content of the raw materials obtained by this rice bran pretreatment process is as high as about 17%. If the water content is too high, it will directly affect the subsequent process of granulation, and the leaching workshop will consume a lot of solvents.

In addition, there are some small improvements to the pretreatment process of rice bran, such as increasing the temperature or time of frying rice bran, but most of the effects are not ideal. Too high temperature or too long time will cause rice in rice bran Oil inactivation affects the extraction amount and quality of rice oil
