Freeze-dried food scrap removing and bagging device

Abstract

The utility model discloses a freeze-dried food scrap removing and bagging device which comprises a conveying belt assembly, a filter screen is arranged on one side of the left side and the right side of the conveying belt assembly in the length direction of the conveying belt assembly, and a plurality of fans are arranged on the side, opposite to the filter screen, of the left side and the right side of the conveying belt assembly. A collecting tank is arranged on the side, where the filter screen is located, of the conveying belt assembly. When freeze-dried food passes through the draught fan on the conveying belt assembly, residues and chippings doped in the freeze-dried food can be blown up towards the filter screen under the action of the draught fan, and due to the fact that the sizes of the residues and the chippings are small, the residues and the chippings can pass through the filter screen and are collected under blowing of the draught fan, and therefore the residues and the chippings are collected. Therefore, the freeze-dried food which finally enters the freeze-drying hopper and is packaged is subjected to residue and chipping removal, and the product quality is improved.

Description

Technical Field

[0001] This utility model relates to the technical field of freeze-dried food bagging equipment, specifically to a freeze-dried food desiccant bagging device. Background Technology

[0002] Freeze-dried food, also known as vacuum freeze-dried food or FD food, is produced by rapid freezing and vacuum dehydration, which preserves the original color, aroma, flavor, nutrients, and appearance. It also has good rehydration properties, can be stored at room temperature for more than 5 years without preservatives, and is lightweight, making it easy to carry and transport.

[0003] After freeze-dried food processing, a bagging machine is usually used for bagging. For example, the Chinese utility model patent with application number 202323266069.2 and patent name "An Automatic Bagging Machine for Freeze-Dried Food" discloses that: This utility model is equipped with an arc block, a movable block, a pneumatic cylinder, a connecting shaft, and a movable barrel. The movable barrel can prevent the packaging bag from tipping over. When the pneumatic cylinder is running, it will cause the movable plate to move downward. Through the cooperation between the movable plate and the connecting shaft, the two movable blocks can move in opposite directions, thereby clamping and fixing the movable barrel through the arc block and the movable block, so that the movable barrel will not move accidentally and cause the freeze-dried food to fall outside the packaging bag, thus ensuring that the freeze-dried food is completely inside the packaging bag.

[0004] However, before the freeze-dried product is placed into the freeze-drying hopper, some residue and debris are usually generated during the production, processing and transportation process due to vibration and collision. Packing these residues and debris into the packaging bag together will affect the quality of the product. Utility Model Content

[0005] This application provides a descrambling and bagging device for freeze-dried food, which can solve the problem that the quality of the product is affected by including some residues and debris generated by vibration and collision during the production, processing and transportation of freeze-dried food into the packaging bag.

[0006] This application provides a freeze-dried food descrambling and bagging device, including a bagging machine body and a conveyor belt assembly. The conveyor belt assembly is arranged horizontally to transport the freeze-dried food into the freeze-drying hopper of the bagging machine body. A filter screen is arranged on one of the left and right sides of the conveyor belt assembly along the length of the conveyor belt assembly, and the filter screen extends upward from the top surface of the conveyor belt assembly. Multiple fans are arranged on the side of the left and right sides of the conveyor belt assembly opposite to the filter screen. The multiple fans are arranged in a row along the length of the conveyor belt assembly, and all the fans are facing the filter screen. When the freeze-dried food passes over the fans on the conveyor belt assembly, the residues and debris mixed in are relatively light, so they are blown towards the filter screen by the fans. Since the residues and debris are small in size, they pass through the filter screen under the blowing of the fans. A collection trough is provided on the side of the conveyor belt assembly where the filter screen is located to collect the residues and debris after passing through the filter screen.

[0007] In one embodiment, a baffle is fixedly installed on the upper end of the collection tank on the side opposite to the filter screen.

[0008] In one embodiment, the inner bottom surface of the collection tank is inclined to the horizontal plane, and a through groove penetrating the tank wall is provided at the lowest point of the inner bottom surface. A collection box is provided on the outside of the through groove for collecting the residue and debris that rolls down in the collection tank.

[0009] In one embodiment, the collection box is detachably connected to the through groove via a threaded connection.

[0010] In one embodiment, the filter screen has a retaining edge extending forward on the side near the freeze-drying hopper.

[0011] In summary, the freeze-dried food descrambling and bagging device of this application has the following advantages compared with the prior art: when the freeze-dried food passes the fan on the conveyor belt assembly, the residues and debris mixed in therein will be blown towards the filter screen by the fan. Since the residues and debris are small in size, they will pass through the filter screen and be collected by the fan, so that the freeze-dried food that finally enters the freeze-drying hopper and is packaged has undergone the removal of residues and debris, thus improving the quality of the product.

[0017] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. These embodiments are used to illustrate this utility model but are not intended to limit its scope. Furthermore, the described embodiments are only a part of the embodiments of this disclosure, not all of them.

[0019] Please see Figure 1 A bagging and desiccant bagging device for freeze-dried food includes a bagging machine body 1. The specific structure and working principle of the bagging machine body 1 are existing technologies and will not be described in detail here.

[0020] Please see Figure 1 , Figure 2In one embodiment, a conveyor belt assembly 3 is included. The conveyor belt assembly 3 is arranged horizontally and is used to transport the freeze-dried food forward to the freeze-drying hopper 2 of the bagging machine body 1. The specific structure and working principle of the conveyor belt assembly 3 are existing technologies and will not be described in detail here. A row of filter screens 6 is fixedly installed along the length of the conveyor belt assembly 3 at the left edge of the conveyor belt 4. The filter screens 6 can be fixedly connected to the frame 5 of the conveyor belt assembly 3 by welding, and the filter screens 6 extend upward from the top surface of the frame 5.

[0021] Please see Figure 1 , Figure 2 Multiple fans 8 are installed on the right side of the conveyor belt assembly 3 via threaded connections. These fans 8 are arranged in a row along the length of the conveyor belt assembly 3, all facing left. The positions of the fan 8 sections correspond to the filter screen 6 sections, and the total length of the filter screen 6 sections is slightly greater than the total length of the fan 8 sections. With this arrangement, when freeze-dried food passes over the fans 8 on the conveyor belt assembly 3, the lighter residues and debris will be blown towards the filter screen 6 by the fans. Because of their small size, these residues and debris will pass through the filter screen 6 under the airflow. Freeze-dried food, generally heavier, will not be easily blown away by the fans 8. Even if some smaller freeze-dried food items are blown to the left, their larger size will prevent them from being blocked by the filter screen 6. Furthermore, the fan 8 can be set to blow air at the same interval, that is, blow for a period of time, then stop for a period of time, then blow for a period of time again, then stop for a period of time again, and so on. This setting can prevent some small freeze-dried foods from being blocked on the filter screen 6 under the action of the fan 8, and the effect is better.

[0022] Please see Figure 2 , Figure 3 A collection trough 9 is fixed on one side of the conveyor belt assembly 3 where the filter screen 6 is located. The opening of the collection trough 9 faces upward. The total length of the collection trough 9 is slightly greater than the total length of the filter screen 6. It is used to collect the residue and debris that have passed through the filter screen 6 (screened out by the filter screen 6).

[0023] Please see Figure 1 In one embodiment, a baffle 13 is welded to the upper end of the collection tank 9 on the side opposite to the filter screen 6 (the collection tank 9). The length of the baffle 13 is greater than the total length of the filter screen 6 segment, and the top of the baffle 13 is higher than the filter screen 6. With this arrangement, the baffle 13 can play a blocking role, preventing the residue and debris after passing through the filter screen 6 from being blown out of the collection tank 9 and thus unable to be collected.

[0024] Please see Figure 2 , Figure 3 In one embodiment, the inner bottom surface of the collection tank 9 is inclined to the horizontal plane. A through-slot 10 penetrating the tank wall is provided at the lowest point of the inner bottom surface. A collection box 11 is provided on the outer side of the through-slot 10, with its opening facing upwards and its sidewall connected to the through-slot 10, for collecting residues and debris rolling down from the collection tank 9. This arrangement ensures that residues and debris blown into the collection tank 9 will eventually roll down the inclined bottom of the tank into the collection box 11, making the process more convenient.

[0025] Please see Figure 2 , Figure 3 In one embodiment, the collection box 11 is detachably connected to the through groove 10 by means of a threaded connection. With this configuration, the collection box 11 can be installed or removed by screwing in or out the bolts 12. The structure is easy to implement and the operation is relatively simple.

[0026] Please see Figure 1 , Figure 2 In one embodiment, the filter screen 6 is fixedly provided with a baffle 7 extending forward on the side near the freeze-drying hopper 2. The baffle 7 extends to the freeze-drying hopper 2. This arrangement is because some freeze-dried foods with smaller mass are easily blown to the filter screen 6 by the fan 8 and remain there to move forward. The baffle 7 can prevent these freeze-dried foods from falling off the conveyor belt 4 from this side.
