Improved structure of discharge mechanism of turndown type fermented soybean meal drying machine

Abstract

The invention relates to an improved mechanism of a device for drying soybean meal obtained by extracting soybean oil from soybeans after fermentation, in particular to the improved structure of a discharge mechanism of a turndown type fermented soybean meal drying machine, a hole is formed at the middle section of a vertical main air pipe (6) which is near to the side of a discharge gate (12), aby-pass pipe (10) is connected in the form of a three way, and a first gate is arranged in a passage of the by-pass pipe (10); a second gate is arranged between the by-pass pipe and an air outlet andcollection cover (5) in the passage of the vertical main air pipe (6); the first gate is closed and the second gate is opened during the drying and turndown operation; and the first gate is opened and the second gate is closed during the discharge operation. The improved structure can lead an airflow loop in a system to change, blow materials in the drying machine to be discharged from an outlet along the airflow in a forced manner, and solve the difficult problem of non-smooth and non-complete discharge by utilizing the airflow of a fan of the drying machine and by increasing a by-pass pipeline and a pneumatic door-turning mechanism for carrying out ingenious switching.

Description

technical field [0001] The invention relates to an improved mechanism of equipment for drying soybean dregs obtained by extracting soybean oil after fermenting them, in particular to an improved structure of a discharging mechanism of a turning-type fermented soybean dregs dryer. Background technique [0002] Soybean meal is a by-product of soybean oil extracted from soybeans. It is very nutritious and has always been a bulk protein raw material in the feed industry and aquaculture industry. The protein absorption and conversion rate of soybean meal is low, and it causes severe damage to the immune system and digestive system of animals, especially high-grade aquatic animals, affects the nutritional value of soybean meal, and causes the waste of soybean meal protein feed. Using bio-fermentation technology to denature soybean meal, eliminate anti-nutritional factors, increase beneficial ingredients and small peptides, and improve the utilization rate of soybean meal, has beco...

Problems solved by technology

Therefore, the disadvantages are: after the drying operation, a large amount of fermented soybean meal has been accumulated on the ventilating hole plate; It is conveyed to the discharge side, which affects the conveying speed and affects the work efficiency; moreover, because the fermented soybean meal left over from the previous batch of drying process is mixed with the new batch of fermented soybean meal to be dried, it also affects the drying process of the next batch. Dry quality, part of the fermented soybean meal will be over-dried, while some will be under-dried, which will even affect the quality of subsequent high-quality suckling pig feed and aquatic feed

[0008] That is to say, due to the different particle sizes of the fermented soybean meal powder material, the moisture difference before and after drying is large, so that the bulk density of the material becomes larger after drying and tends to stay in the lower part of the orifice plate of the dryer, resulting in long discharge time and poor discharge of some materials. Unclean phenomenon, repeated drying of some materials not only causes energy waste, but also affects product quality

[0009] Someone once proposed an improvement plan to increase the number of turning paddles on the turning shaft and increase the angle of the turning paddles, so as to push the dried fermented soybean meal toward the discharge bin. However, because the turning paddles It is plate-shaped, and its main function is to loosen the fermented soybean meal during the drying process. It is not necessary and impossible to completely contact with the ventilation hole plate. Therefore, it is still difficult to increase the number and angle of the turning blades Cleaner pushing and unloading, and mechanical pushing and unloading will push and compact the fermented soybean meal, which is not good for subsequent processing

Furthermore, adopting this method increases the weight and power consumption of the turning mechanism, and the mechanism becomes bulky and complicated, which is not a method accepted by users
