Description
Technical Field
The application belongs to the field of food processing equipment, and particularly relates to a modulation system of an energy-saving soybean tempering tower.
Background
In recent years, soybean peeling technology is widely applied, the technology aims at producing soybean meal with high protein content and improving the quality of soybean oil, and can obtain soybean seed coats rich in fibers, so that the technology is an important way for improving the economic benefit of an oil factory, a soybean tempering tower is key equipment in the soybean peeling technology, soybeans enter the soybean tempering tower for treatment after being cleaned, and not only can heat, temper and soften the soybeans, but also can reduce the water content of the soybeans in a short time, so that the soybeans meet proper temperature, humidity and physical characteristics required by peeling and embryo rolling, and the technology is a combination of functions of a softening pot and a dryer. The soybean peeling process is basically adopted in the production line of soybean newly built in the existing medium-large oil factory, so that the soybean tempering tower becomes the standard of the medium-large soybean oil factory.
The soybean tempering tower has the working principle that steam is used for indirect heating and hot air is used for direct drying and dehydration. The indirect steam heating not only improves the temperature of the soybeans to fully soften the soybeans, but also plays a role in drying and dewatering the soybeans, and the hot air directly contacts the soybeans in a convection mode to remove the humidity of the soybeans and take away water vapor, and also plays a role in heating and raising the temperature of the soybeans.
The soybean tempering tower is in a building block structure, the same series is designed and manufactured in a modularized mode, different module numbers are used according to different yields, and products are transported in a module mode and assembled on site. The main structure of the soybean tempering tower consists of multiple layers, and comprises a feeding section 1', a heating layer 2', a hot air layer 3', a discharging section 4' and a control system, wherein the heating layer 2 'and the hot air layer 3' are arranged at intervals (see figure 1); the heating layers 2' are arranged in a staggered way by adopting elliptical pipes and heated by low-pressure steam (see figure 2); the hot air layer 3' adopts an angular ventilation box (see fig. 3); the discharging section consists of several groups of rotary valves.
The control system is automatic control, the material level of the feeding section is controlled by the discharging section and is interlocked with the feeding conveying equipment, the steam inlet amount of the steam layer is controlled by the temperature of soybean in the discharging section, and the hot air temperature or the hot air amount of the hot air layer is controlled by the humidity content of soybean in the discharging section.
The main advantages of the soybean tempering tower are: the soybean peeling machine is beneficial to the soybean thermal peeling process, has good peeling effect, does not need reheating and dewatering before leaching, saves embryo piece drying equipment, and can save power consumption compared with a softening pot.
The main problems of the soybean tempering tower are as follows:
(1) And the steam consumption is high. The existing soybean tempering tower uses indirect steam heating to temper and soften soybeans in a heating layer, hot air is blown into a hot air layer to dry the soybeans, the hot air is heated by an air heater, and the air heater is indirectly heated by steam. The automatic control system controls the steam inlet amount of the steam layer according to the temperature of the soybean in the discharging section, and controls the hot air temperature of the hot air layer according to the humidity content of the soybean in the discharging section, namely, controls the steam inlet amount of the air heater, which is equivalent to the steam heating layer only considering steam heating, and the hot air drying layer only considering humidity removal. From the working principle of the soybean tempering tower, the heating layer elliptical tube is used for indirectly heating, so that the soybean temperature is increased, the soybean is dried and dehydrated, the hot air is directly contacted with the soybean in a convection way, the soybean humidity is removed, the moisture is taken away, and the soybean is heated. Therefore, the calculated steam demand set by the automatic control system is larger than the actual demand, so that the steam quantity is often input excessively during production, certain steam waste is caused, and the steam consumption is high.
(2) The manufacturing cost of the equipment is high, the materials are more, and the volume is large. The main structure of the soybean tempering tower consists of a plurality of layers, and comprises a feeding section, a heating layer, a hot air layer, a discharging section and other structures, wherein the heating layer and the hot air layer form a tempering section, the soybean is heated, tempered and softened, then the soybean is dried and dehumidified, the soybean tempering tower is formed by combining a plurality of tempering sections, and repeated tempering, softening and drying operations are carried out, so that the equipment height is higher, the height diameter is larger, and the number of tempering sections required for achieving the required tempering and drying requirements is also larger. The excessively high height puts higher demands on the workshop, and also on the height of corresponding matched equipment such as a feeding elevator, which increases the investment of the workshop and the equipment.
(3) The method is only applied to a soybean peeling process, cannot be applied to other raw materials and other oil pretreatment processes, and has a small application range. The soybean tempering tower is specially used in soybean peeling technology, and is used for softening and drying soybean so that soybean hulls and kernels can be separated to facilitate subsequent peeling, grains such as corn, wheat, rice and the like cannot be dried, because the temperature of a heating layer is too high for the grains, the surface layer of the processed grains is quickly dried, the internal humidity is not reduced, the surface is excessively dried and crushed, the internal is moist, the grains are damaged and are not beneficial to storage, and if the grains are simply dried by a drying layer, the drying capability is insufficient, the internal volume is seriously wasted, and the effect is poor. The softening and drying treatment of other oil materials has great defects, such as softening and drying only when the rapeseed pretreatment process is adopted, and insufficient drying capability and poor effect when the rapeseed is required to be dried. Other oil pretreatment processes or drying processes are similar to those of rapeseed.
