Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of silo ventilation and unloading and fragmentation, and particularly relates to a cocoa bean silo ventilation and fragmentation integrated device. BACKGROUND

[0002] Cocoa beans are an important agricultural product, and their processed products are widely used in the food and beverage, cosmetic, and pharmaceutical industries worldwide. These products, including cocoa liquor, cocoa butter, and cocoa powder, are not only key raw materials for the food industry, but also play an important role in daily life.

[0003] Cocoa bean processing capacity is mainly concentrated in Europe and the United States, and raw materials are basically from Africa. Some cocoa processing plants have found problems, problem one: the breakage rate of raw cocoa beans is high during cleaning, temporary storage, and packaging; problem two: because the cocoa beans pass through hot air drying before entering the silo for temporary storage, the temperature of the cocoa beans is relatively high, and the temperature of the cocoa beans before packaging cannot be effectively reduced to below 35 degrees, which will cause the packaged cocoa beans to be prone to moisture, mold, and clumping. These problems directly reduce the quality of cocoa beans (cocoa bean quality is divided according to international export grades as shown in the table above), affecting foreign trade prices. Therefore, there is an urgent need for a cocoa bean silo ventilation and fragmentation integrated device to solve the above problems. SUMMARY

[0004] The utility model aims at providing a cocoa bean silo ventilation and fragmentation integrated device, which increases a ventilation and fragmentation integrated device in the temporary storage silo, uses a spiral unloading chute to make the cocoa beans slowly slide to the bottom of the silo, and sets a ventilation hole in the spiral shaft at the center of the spiral unloading chute to synchronize ventilation, so that fresh air and the sliding cocoa beans are blown to exchange heat. The cocoa beans continue to be ventilated through the ventilation hole during temporary storage in the silo, and the temperature and humidity of the cocoa beans are effectively controlled and the breakage rate of the cocoa beans during unloading is reduced through ventilation and fragmentation measures.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme:

[0006] A cocoa bean silo ventilation and fragmentation integrated device increases a ventilation pipe, a spiral unloading chute, a silo top connecting flange, and a silo bottom support frame in the cocoa bean silo.

[0007] The ventilation pipe is connected with an external ventilation fan, fresh air is ventilated to the silo through the ventilation pipe to adjust the temperature and humidity of the cocoa beans in the silo; the top of the spiral unloading chute is connected with a feeding pipe to make the cocoa beans entering the silo slide along the spiral unloading chute to the bottom of the silo, reduce the potential energy of the cocoa beans falling from a high place, and reduce the breakage of the cocoa beans during temporary storage after cleaning; the silo top connecting flange is connected with the top of the cocoa bean silo through bolts, and the silo bottom support frame is connected with the inner wall of the cocoa bean silo through bolts.

[0008] Further, the ventilation pipe is a stainless steel pipe, and the pipe is densely provided with ventilation holes of 6 mm. The size of the ventilation holes is smaller than the particle size of the cocoa beans (the size of the cocoa beans is not less than 10 mm), so that the ventilation holes are not blocked.

[0009] Further, the pitch-diameter ratio of the spiral discharge chute is equal to 1, that is, pitch:diameter=1.

[0010] At present, the common silo ventilation and crushing method is that ventilation is provided at the bottom of the silo, and the crushing chute is a supporting wall return type chute attached to the silo wall. Compared with the prior art, the present application has the following advantages:

[0011] 1. The spiral discharge chute is used for the cocoa beans to slide to the bottom of the silo, and there is no crushing phenomenon caused by repeated impact, so that the crushing of the cocoa beans during the temporary storage process is eliminated to the greatest extent, and the quality of the cocoa beans is improved.

[0012] 2. The ventilation pipe with densely punched holes is used in the middle of the spiral chute, so that the cocoa beans are ventilated and heat-exchanged with fresh air during the sliding process, the residual heat after the previous drying process is discharged outside the silo after heat exchange to the greatest extent, the temperature and humidity of the cocoa beans in the silo are effectively reduced, and the phenomena of moisture return and mildew of the cocoa beans during the subsequent storage are reduced.

[0013] 3. The ventilation and crushing are integrated, ventilation and heat exchange are performed by using the spiral shaft, no additional device is needed, good economic benefits are obtained, and the ventilation and crushing requirements of the cocoa bean silo are fully combined, the crushing chute is arranged in the middle of the silo, cocoa beans are uniformly distributed to the four sides of the silo, ventilation is performed during discharging, and ventilation and heat exchange are more sufficient.

[0014] 4. The ventilation and crushing device has the advantages of simple structure, small size, convenient installation and wide application range. BRIEF DESCRIPTION OF DRAWINGS
