Description

Technical Field

[0001] The invention relates to a processing production line for producing powdered functional food using plant raw materials, which is suitable for the deep processing industry of agricultural products and can be widely used in the industrialized production of tourism and leisure fast food, disaster relief food, military food and aerospace food. Background Art

[0002] The production and processing system for processing powdered functional foods with fruits and vegetables as raw materials generally includes: a cleaning machine, a crusher, a forming machine, a drying machine, a shredder, a cooling chamber and a pneumatic cyclone - a spiral blade cooler. The disadvantage of this system is that the cooling of the dried product is carried out in the unloading area, which affects the color and quality of the finished product to a certain extent. In addition, this device cannot process fruit and vegetable powders with high soluble carbohydrates and high moisture content (60-65%). In addition, the surface of the finished product is easily affected by moisture during transportation, resulting in a layer of film-like substance. During the grinding process, the grinding and breaking devices are also prone to adhesion, thereby reducing the production capacity and product quality of the system device and reducing the process production capacity of the system equipment.

[0003] The latest technological solution for the production of dried food products from fruits with a high soluble carbohydrate content (e.g. bananas) is a system that includes the following devices and installs them in series according to the process flow: a washing machine, an inspection conveyor, a slicer, a raw material pre-cooking device, a raw material post-cooking cooling device, a dryer, a grinder and a packaging device.

[0004] The existing traditional powdered food processing and production equipment system can generally only produce single raw material products, and cannot produce compound raw material products. Moreover, using such equipment to produce powdered functional foods consumes a lot of energy when heat treating and drying plant raw materials, causing environmental pollution and increasing product production costs. Summary of the invention

[0031] The outlet ends of the first conveyor belt 201 and the second conveyor belt 202 are respectively provided with lifting conveyors 200 .

[0032] The first weight quantitative feeder 81 and the second weight quantitative feeder 82 are respectively connected to the inlet of the mixer 9; the inlet of the mixer 9 is connected to the inlet of the raw material distributor 10; the outlet of the raw material distributor 10 is located directly above the conveyor belt 11, so that the raw material distributor 10 can distribute the raw materials to the cart on the conveyor belt 11.

[0033] The dehydration and drying area includes a dual-zone dryer 14, a conveying track 13 and a trolley 12 with a tray. The dual-zone dryer 14 is provided with a fan 15. One zone of the dual-zone dryer 14 is dried by a heat generator 16, and the second zone is dried by an air energy heat pump device 17. One end of the conveying track 13 is connected to the heat generator 16, and the other end is connected to the air energy heat pump device 17; the trolley 12 is arranged on the conveying track 13. The drying temperature of the air energy heat pump device 17 is 60°C; the drying temperature of the heat generator 16 is 100°C.

[0034] The cooling area is provided with a cooling device 18; the crushing area is provided with a grinder 20, and the cooling device 18 is connected to the grinder 20 through an elevator 19; the screening area is provided with a vibrating screen 21, and the vibrating screen 21 adopts a cylindrical vibrating screen, and the vibrating screen 21 has a drum-type large and small hole screen; the finished product packaging area is provided with a bag sewing machine 22.

[0035] The production line of the present invention for producing powdered functional food using plant raw materials has the following production process during processing:

[0036] The plant raw materials are put into the first feeding trough 101, and the plant raw materials are put into the drum cleaning machine 3 through the lifting conveyor 200 at the outlet end of the first conveyor belt 201. Then, the unqualified raw materials are removed by the first magnetic sorting conveyor 51, and the qualified raw materials are put into the plant raw material peeling machine 6. After that, they pass through the first plant raw material cutting machine 71, and are sent to the first weight quantitative feeder 81 after cutting.

[0037] While the above process is being carried out, another kind of plant raw material is added to the second feeding trough 102, and the plant raw material is fed into the fan cleaning machine 4 through the lifting conveyor 200 at the outlet end of the second conveyor belt 202. Then, the second magnetic sorting conveyor 5 removes unqualified raw materials and feeds qualified raw materials into the second plant raw material cutting machine 72, which is then sent to the second weight quantitative feeder 82 after cutting.

[0038] After completing the above steps, a certain amount of plant raw material powder is output from the first weight quantitative feeder 81 and the second weight quantitative feeder 82 respectively and put into the mixer 9, where a composite plant mixed raw material is obtained, and then enters the next step, the mixed raw material is put into the spiral raw material distributor 10, and then the mixed raw material is placed on the trolley 12 with a pallet through the conveyor belt 11 with a pallet, and transported to the first zone of the dual-zone dryer 14 through the conveying track 13. The heat carrier medium of the heat generator 16 in this zone has a temperature of 100°C under very high humidity conditions. After that, the trolley 12 will transport the raw materials to the second zone of the dual-zone dryer 14. The second zone is equipped with an air energy heat pump equipment 17 with a temperature of 60°C.

[0039] The obtained product raw materials then enter the cooling equipment 18 in the cooling area, and after cooling, they are transported to the grinder 20 by the elevator 19, where the raw materials are ground, and the particles collide with each other in the grinder and with the inner wall of the machine in the device. The obtained powder enters the lower part of the grinder through the fence, and then is screened by the vibrating screen 21 with a drum-type large and small hole screen. The obtained powder is packed into food packaging bags according to the set weight and sealed by the bag sewing machine 22, and finally the finished product is sent to the finished product warehouse.

[0040] In the processing production line of the present invention for producing powdered functional foods using plant raw materials, the peeling processing station and the cutting processing station constitute two raw material processing lines, and the raw materials can be two different raw materials, such as beets and rhubarb. The system is equipped with a two-zone drying device (i.e., a dual-zone dryer), one zone is a heat generator, and the second zone is an air-energy heat pump device. By configuring a two-zone drying device and combining it with heat carrier heating, the water evaporation intensity is controlled and adjusted to ensure product quality, reduce energy consumption, and then effectively reduce product costs and improve product benefits. The dryer with a heat generator in the first zone achieves the purpose of heating function, and the energy efficiency ratio coefficient of the air-energy heat pump equipment equipped in the second zone can reach 4-5. By adopting a heat pump system device, the entire flexible production line system can effectively reduce energy consumption by more than 2 times compared with the production system using traditional heat sources.
