Problems solved by technology

Because imported soybean skins may carry pathogenic species from abroad, unripe soybean skins added to soybean meal to feed animals may produce unpredictable animal diseases, and even spread to humans, causing harm. Therefore, there is an urgent need for a The aging and sterilization method of imported soybean skin

Embodiment Construction

[0019] Such as figure 1As shown, the method for ripening and sterilizing bean curds of the present invention includes the following steps in turn: the bean curds separated by the soybean peeler with a bulk density of 0.08 to 0.12 t / m are sent to the hammer mill 1, and are pulverized by the hammer After being crushed by machine 1, the diameter of bean curd reaches 3.5mm or less, and the bulk density of bean curd increases to 0.15-0.35t / m3. In the case 1a; the crushed bean curd also enters the feed case 1a, and the conveying auger 4 sends the bean curd in the feed case 1a into the bucket elevator 5, and is lifted up by the bucket elevator 5 and enters the buffer storehouse 6, from After the buffer bin 6 is discharged, it is sent to the conditioner 8 by the feeding auger 7, and the saturated steam of 0.3MPa~1.0Mpa enters the conditioner 8 to perform high-temperature curing and sterilization of the bean curd, and the moisture content of the cured and sterilized bean curd is 11%~1...

Abstract

The invention relates to a method of beancurd skin curing and sterilization. The method includes the steps: feeding beancurd skin with the volume weight of 0.08-0.12t / m<3> into a hammer mill to be milled into the beancurd skin with the diameter less than or equal to 3.5mm and the volume weight increased to 0.15-0.35t / m<3>, feeding the milled beancurd skin into a feed bin, feeding the beancurd skin into a cache bin via a conveying screw and a bucket elevator, feeding the bucket elevator into a conditioner via a feeding screw, subjecting the beancurd skin to high-temperature curing sterilization with saturated vapor under the pressure of 0.3MPa-1.0Mpa to enable the beancurd skin to be 11%-17% in moisture content and 100 DEG C-120 DEG C in temperature, and then sequentially feeding the beancurd skin into a first drying layer, a second drying layer and a cooling layer of a vertical drying tower; drying the beancurd skin with hot air at the temperature of 60-120 DEG C in the first and second drying layers till the moisture content is 7-10% and the temperature is 50-100 DEG C; cooling the beancurd skin in the cooling layer till the temperature is not higher than natural air temperature 10 DEG C prior to feeding the beancurd skin into a bent scraper conveyor, and feeding blowdown of drying air and cooling air into the bent scraper conveyor as well. By the method, pathogenic species in the beancurd skin can be killed, and feed security is guaranteed.

Description

technical field [0001] The invention relates to a method for ripening and sterilizing soybean hulls, belonging to the technical field of grain or feed processing. Background technique [0002] At present, the common way for oil extraction factories to process imported soybean skins is to crush and peel them, then crush them, add them directly to soybean meal, and then package them for sale. The soybean skins have not undergone sufficient high-temperature sterilization. Because imported soybean skins may carry pathogenic species from abroad, unripe soybean skins added to soybean meal to feed animals may produce unpredictable animal diseases, and even spread to humans, causing harm. Therefore, there is an urgent need for a The aging and sterilization method of imported soybean hulls. Contents of the invention [0003] The object of the present invention is to overcome the problems in the prior art and provide a method for aging and sterilizing soybean hulls, which can kill ...
