Description

Technical Field

[0001] This utility model relates to the field of cold storage technology, and in particular to a high-efficiency and practical clean cold storage. Background Technology

[0002] With the rapid development of modern food, pharmaceutical, and biotechnology industries, the requirements for product storage environments are becoming increasingly stringent. Cold storage facilities, as crucial storage facilities, not only need to maintain low temperatures but also ensure cleanliness. In the food industry, for fresh fruits and vegetables, meat, and dairy products, unclean cold storage environments can easily lead to microbial growth, causing food spoilage, shortening shelf life, and resulting in significant economic losses. For example, in dairy product storage, bacterial contamination can cause product rancidity and off-odors, severely affecting product quality and sales. In the pharmaceutical field, medicines and vaccines have extremely high requirements for storage conditions. Uneven temperatures and substandard cleanliness can lead to drug ineffectiveness, endangering patients' lives. Taking vaccines as an example, temperature fluctuations and microbial contamination during cold chain transportation and storage can reduce vaccine activity, preventing it from achieving the desired immunization effect.

[0003] In existing technologies, conventional clean cold storage facilities typically use internal surface coolers for heat exchange to control the temperature. Since the air inside the cold storage cannot be purified, air filtration boxes are generally used to purify the air, filtering it before delivery to improve cleanliness. However, this approach has several drawbacks: 1. Uneven temperature distribution leads to non-compliance with temperature uniformity standards; 2. The presence of refrigeration and filtration equipment makes the cold storage prone to microbial growth, potentially exceeding cleanliness standards; 3. Air filtration boxes cannot purify all air, creating dead zones and occupying space, while their own fans generate heat, affecting the temperature; 4. Maintenance of the refrigeration unit's surface cooler and air filtration fans is inconvenient and can cause environmental pollution; 5. Cold storage equipment requires re-sterilization after maintenance, increasing production costs. Utility Model Content

[0004] This utility model mainly provides a highly efficient and practical clean cold storage.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high-efficiency and practical clean cold storage, comprising a cold storage body, a buffer box disposed above the cold storage body, an internal cooling fan and a supply fan disposed inside the buffer box, a high-efficiency air outlet disposed on the lower end face of the supply fan, a primary filter wall disposed inside the buffer box, a return air outlet disposed inside the cold storage body, the return air outlet being connected to the buffer box via a return air duct, return air louvers disposed inside the buffer box, and an inspection door disposed on the side of the buffer box.

[0006] Preferably, the high-efficiency air outlet consists of a high-efficiency filter and a diffuser.

[0007] Preferably, the buffer box is connected to the return air duct via return air louvers.

[0008] Preferably, a buffer room and an air shower are provided on the side of the buffer box.

[0009] Preferably, the buffer room and the air shower room are arranged adjacent to each other, and both are located on the side of the buffer box where the inspection door is located.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0011] 1. In this utility model, by moving the surface cooler and air filter unit originally located inside the cold storage to a buffer box, the air is cooled in the buffer box by the internal cooling fan, then diffused to the cold storage body through the high-efficiency air outlet by the air supply fan, and then returned to the buffer box through the return air outlet, return air duct and return air louvers. Finally, it enters the internal cooling fan for cooling after passing through the primary filter wall, completing continuous circulation and purification. This effectively solves the problem of uneven temperature distribution in conventional cold storage, improves the temperature uniformity of the cold storage, and makes it meet the specifications. At the same time, the dual filtration of the high-efficiency filter and the primary filter wall improves the cleanliness of the cold storage and reduces the risk of microbial contamination.

[0012] 2. In this utility model, by setting a buffer room and an air shower on the side of the buffer box, and arranging them adjacently and located on the side where the inspection door is located, maintenance personnel and tools can first undergo self-cleaning in the air shower to remove dust and microorganisms before entering the buffer box for equipment maintenance, and then transition into the buffer box through the buffer room. This not only improves the maintenance efficiency of cold storage equipment, but also reduces the risk of microbial contamination during equipment maintenance, and avoids the need for re-disinfection after maintenance, effectively reducing maintenance costs.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0019] Please see Figures 1-3 This utility model provides a technical solution: a high-efficiency and practical clean cold storage, including a cold storage body 1, a buffer box 2 installed above the cold storage body 1, a refrigeration internal fan 3 and a blower 4 installed inside the buffer box 2, a high-efficiency air outlet 5 installed on the lower end face of the blower 4, a primary filter wall 6 installed inside the buffer box 2, a return air outlet 7 installed inside the cold storage body 1, the return air outlet 7 is connected to the buffer box 2 through a return air duct 8, a return air louver 9 is installed inside the buffer box 2, and an inspection door 10 is installed on the side of the buffer box 2.

[0020] like Figure 1 As shown, the high-efficiency air outlet 5 consists of a high-efficiency filter and a diffuser.

[0021] like Figure 1 As shown, the buffer box 2 is connected to the return air duct 8 via the return air louver 9.

[0022] like Figure 3 As shown, a buffer chamber 11 and an air shower chamber 12 are provided on the side of the buffer box 2.

[0023] like Figure 3 As shown, the buffer room 11 and the air shower room 12 are arranged adjacent to each other, and both are located on the side of the buffer box 2 where the inspection door 10 is located.

[0024] The operating method and working principle of this device are as follows: When using this high-efficiency and practical clean cold storage, firstly, start the internal cooling fan 3 to cool the air in the buffer box 2. The cooled air, under the action of the blower 4, enters the cold storage body 1 through the high-efficiency air outlet 5 (composed of a high-efficiency filter and a diffuser). The high-efficiency filter effectively purifies the air, while the diffuser evenly disperses the air, ensuring uniform temperature distribution and cleanliness within the cold storage body 1. Subsequently, the air in the cold storage body 1, under its own circulation and temperature difference, gathers in the return air duct 8 through the return air outlet 7, and then returns to the buffer box 2 through the return air louvers 9. The air returning to buffer box 2 then passes through the primary filter wall 6, further filtering impurities and microorganisms, before entering the cooling internal fan 3 for cooling. This forms a continuous air circulation and purification process. When maintenance is required on the equipment inside buffer box 2, maintenance personnel and tools first go to the air shower room 12 on the side of buffer box 2. The equipment in the air shower room 12 is turned on, and the high-speed airflow washes and cleans the dust and microorganisms on the surface of personnel and tools. After the air shower is completed, personnel and tools enter the adjacent buffer room 11. After a short transition to adapt to the environment, they enter buffer box 2 through the maintenance door 10 on the same side to begin equipment maintenance work.
