Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of konjac cold storage, specifically to an energy-saving cold storage for konjac storage. Background Technology
[0002] Konjac is a nutritious, low-calorie, and high-fiber food ingredient widely used in food processing, medicine, and chemical industries. However, konjac is prone to spoilage after harvesting, leading to a decline in quality and affecting its efficacy. To maintain the freshness and quality of konjac, it needs to be refrigerated in a cold storage facility.
[0003] Pre-cooling konjac before refrigeration is crucial because it has a high water content and is prone to spoilage during refrigeration. Pre-cooling effectively lowers the temperature of the konjac, slows down microbial growth, and extends its shelf life under refrigeration conditions. Existing cold storage facilities only have refrigeration capabilities, requiring additional refrigeration equipment for pre-cooling the konjac before storage, resulting in high energy costs. Furthermore, the konjac still needs to be transported to the cold storage after pre-cooling, leading to low refrigeration efficiency. Additionally, the konjac warms up during transportation, further diminishing the pre-cooling effect. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1
[0029] Please see the appendix Figures 1-7 This utility model discloses an energy-saving cold storage for storing konjac, including a cold storage body 1, a pre-cooling conveying device 2, a pre-cooling blower assembly 3, and a cold air channel 5, wherein:
[0030] The cold storage body 1 is provided with an inlet chamber 11 and a closed pre-cooling chamber 13, a cold storage chamber 14 and a refrigeration chamber 15. The refrigeration chamber 15 is equipped with refrigeration equipment for refrigeration gas. The pre-cooling chamber 13 is located between the inlet chamber 11 and the cold storage chamber 14. The inlet chamber 11 is connected to the outside.
[0031] The precooling conveyor 2 is installed in the precooling chamber 13 and is used to convey konjac from the storage room 11 to the cold storage room 14;
[0032] The precooling blower assembly 3 includes a precooling blower 31, which is equipped with a conveying air duct 33 and an air outlet duct 34 for the konjac on the air-cooled precooling conveying device 2.
[0033] The cold air passage 5 is connected to the refrigeration chamber 15 and is used to deliver cold air into the air delivery duct 33.
[0034] Please refer to the appendix. Figure 5 , Figure 6 , Figure 7 The precooling conveyor 2 includes a U-shaped conveyor belt 21 with a feeding end 22 and a discharging end 23 on both sides. The feeding end 22 extends out of the precooling chamber 13 and into the storage chamber 11, and the discharging end 23 extends out of the precooling chamber 13 and into the cold storage chamber 14.
[0035] The conveyor belt 21 can transport konjac directly from the storage room 11 through the pre-cooling room 13 to the cold storage room 14. When passing through the pre-cooling room 13, the konjac is pre-cooled, so that the pre-cooled konjac can be directly refrigerated.
[0036] Furthermore, the precooling blowers 31 in the precooling blower assembly 3 are symmetrically arranged and are all located on one side of the precooling chamber 13. The air outlet channels 34 on the symmetrically arranged precooling blowers 31 are respectively aligned with the two parallel straight conveying sections on the U-shaped path conveyor belt 21.
[0037] When the konjac passes through the pre-cooling channel 41, the cold air blown out of the air outlet duct pre-cools the konjac. Since the conveyor belt 21 is U-shaped and the two blowers are installed on the same side, when the konjac passes through the two pre-cooling channels 41, both the front and back sides of the konjac are subjected to the same air-cooling effect.
[0038] Furthermore, each of the symmetrically arranged precooling fans 31 is equipped with an air inlet channel 32 at its bottom, an air inlet pipe 321 is installed in the air inlet channel 32, and a dust filter 322 is installed inside the air inlet pipe 321.
[0039] The filter 322 inside the air inlet duct 321 can prevent dust from entering and prevent dust from falling on the konjac during the air cooling process, thus affecting the quality of the konjac.
[0040] Please refer to the appendix. Figure 1 , Figure 4 It also includes a refrigeration component 6, which includes multiple air ducts 61 fixed to the top of the refrigeration compartment 14, multiple downward-facing air outlet plates 62 installed on the air ducts 61, and multiple storage racks 141 placed inside the refrigeration compartment 14.
[0041] The cold air generated in the refrigeration chamber 15 can be evenly discharged into the refrigerator chamber 14 through the cold air pipe 61 and multiple air outlet plates 62, so that the konjac in the refrigerator chamber 14 is evenly refrigerated and temperature differences in different areas of the refrigerator chamber 14 are avoided.
[0042] Furthermore, the cold storage body 1 is equipped with multiple doors 12, which are respectively connected to the pre-cooling chamber 13, the cold storage chamber 14 and the refrigeration chamber 15.
[0043] Through door 12, one can enter the pre-cooling chamber 13, the cold storage chamber 14, and the refrigeration chamber 15 to maintain the conveyor belt 21, blower, refrigeration equipment, and other equipment in the pre-cooling chamber 13 and the refrigeration chamber 15, and then enter the cold storage chamber 14 through door 12 to store the konjac. Example 2
[0044] Based on the above embodiment one, please refer to the appendix. Figure 6 , Figure 7 The upper end of the conveyor belt 21 is symmetrically equipped with air guide chambers 4 that correspond to and cooperate with the air outlet channel 34. The air guide chambers 4 are equipped with pre-cooling channels 41 that are aligned with the air outlet of the air outlet channel 34. The side end of the pre-cooling chamber 13 is symmetrically equipped with air outlet ducts 7 that correspond to the pre-cooling channels 41.
[0045] The cold air blowing along the pre-cooling channel 41 can make the cold air more concentrated and prevent it from dissipating, thereby improving the pre-cooling effect and rate.
[0046] Furthermore, observation windows 42 are symmetrically installed on the side of the air guide chamber 4. The observation windows 42 are embedded in the air guide chamber 4 and connected to the pre-cooling channel 41.
[0047] The konjac inside the air guide chamber 4 can be observed through monitoring equipment or by directly entering the pre-cooling chamber 13 through the door 12.
[0048] The cold air passage 5 includes a first cold air pipe 51 and a second cold air pipe 52. The first cold air pipe 51 and the second cold air pipe 52 are connected to the refrigeration chamber 15 on one side, and the first cold air pipe 51 and the second cold air pipe 52 are connected to different air delivery ducts 33 on the other side.
[0049] Part of the cold air generated by the refrigeration equipment in the refrigeration chamber 15 enters the two conveying air ducts 33 along the first cold air pipe 51 and the second cold air pipe 52, so that the air blown out of the air outlet duct 34 is cold air, eliminating the need for additional refrigeration equipment and reducing equipment costs.
[0050] The operation process and principle of this utility model are as follows: The konjac to be stored is placed from the storage chamber 11 onto the feeding end 22 of the conveyor belt 21. At this time, the conveyor belt 21 transports the konjac to the pre-cooling chamber 13. Simultaneously, the blower starts and blows air into the pre-cooling channel 41 above the conveyor belt 21 through the conveying pipe and the air outlet channel 34. Part of the cold air generated by the refrigeration equipment in the refrigeration chamber 15 enters the two conveying air ducts 33 along the first cold air pipe 51 and the second cold air pipe 52, making the air blown out of the air outlet channel 34 cold air. When the konjac passes through the pre-cooling channel 41, the cold air blown out of the air outlet duct pre-cools the konjac. Since the conveyor belt 21 is U-shaped and the two blowers are installed on the same side, when the konjac passes through the two pre-cooling channels 41, both the front and back sides of the konjac are subjected to the same air cooling effect. After the konjac passes through the two pre-cooling channels 41, the pre-cooling is completed. The pre-cooled konjac is transported along the conveyor belt 21 to the conveyor discharge end 23 in the cold storage room 14. At this time, the staff in the cold storage room 14 can directly take off the konjac and store it on the storage rack 141.
