  • Construction of fresh keeping storehouse for fruits and vegetables

    What is fruit and vegetable fresh-keeping storehouse? Cold storage of fruits and vegetables is a kind of storage method which can inhibit the activities of microorganisms and enzymes and prolong the long-term storage of fruits and vegetables. Cold storage technology is the main way to keep fruits and vegetables fresh at low temperature. The fresh-keeping temperature range of fruits and vegetables is 0 ℃~ 15 ℃. The fresh-keeping storehouse can reduce the incidence of pathogenic bacteria and the decay rate of fruits and vegetables, and slow down the respiratory metabolism process of fruits and vegetables, so as to prevent decay and prolong the storage period. What are the advantages of fruit and vegetable storage? 1. Vegetables can be stored for a long time, such as grapes for 6 months, apples for 8 months, garlic moss for 10 months, etc. because of the long preservation period, they can also be sold off season to improve the economic benefits of agricultural products. Moreover, the quality of fruits and vegetables after storage is fresh and tender as before, and the total loss is less than 5%

  • Construction of controlled atmosphere storage

    What is a controlled atmosphere refrigerator? The controlled atmosphere cold storage is based on the cold storage, adding gas composition regulation. Through the control of temperature, humidity, carbon dioxide, oxygen concentration and ethylene concentration in the storage environment, it can inhibit the respiration and self consumption of fruits and vegetables, make them close to dormant state, reduce water loss, reduce disease occurrence, delay their metabolic process, so as to keep them in storage for a long time The texture, color, taste and nutrition of fruits and vegetables are basically unchanged, which can better maintain the freshness of fruits and vegetables and prolong the storage period of fruits and vegetables. The storage period of fruits and vegetables can be prolonged by 2 times and 3 times of the most advanced storage methods in the world. The principle of controlled atmosphere storage

  • Design and construction of shade storehouse

    What is a cool house? The temperature of the cool warehouse is generally 0 ~ 20 ℃, and its main uses are: raw material storage, medicine storage, etc. Ordinary raw materials storage requirements are not very high, ordinary warehouse can add refrigeration equipment to control the temperature, the design of special requirements of drug cool warehouse is more complex. The temperature requirements of drug cool storehouse: according to the national regulations, the temperature of drug cool storehouse is below 20 ℃ and above zero degree, but in the actual use process, the temperature of drug cool storehouse is generally set between 10 ~ 20 ℃. According to the regulations, if there are two storage temperatures for the same drug, it should be stored according to the low temperature standard. Once the drugs in the cold storage of drugs in the process of storage expired, it will cause great economic losses. Before the design and construction of drug shade storehouse: 1

  • Construction of general cold storage

    The common cold storage generally refers to all cold stores except the controlled atmosphere storage. It is mainly composed of heat insulation frame, bottom plate and cold storage, and is mainly composed of heat insulation frame, bottom plate and cold storage Ensure good heat insulation and air tightness of cold storage. The cold storage door can not only be opened flexibly, but also be closed tightly and used reliably. In addition, the wooden parts in the cold storage door should be dried and antiseptic; the cold storage door should be equipped with lock and handle, and the safety unlocking device should be installed; the low-temperature cold storage door frame should be installed with electric heater with voltage below 24 V to prevent condensation water

  • Construction of logistics cold storage

    Cold storage is a warehouse that uses cooling facilities to create suitable humidity and low temperature conditions. Also known as cold storage. It is a place for processing and storing agricultural and livestock products. It can get rid of the influence of climate, extend the storage period of agricultural and livestock products, and regulate the market supply. Aiming at the continuous development and construction of logistics cold storage, Haoshuang refrigeration adopts the situation that most meets the actual work needs of customers. Combining theory with practice and years of experience, Haoshuang provides reasonable refrigeration scheme for customers. Save investment for customers and produce good economic benefits. Logistics cold storage construction steps: first, cold storage location, logistics storage cold storage is generally built according to the development of the enterprise itself in the location of low land price and relatively convenient transportation, around the cold storage should avoid heavy pollution sources, the floor should be flat, hard and dry

  • Construction of quick freezing cold storage

    The construction temperature range of quick freezing storehouse is - 15 ℃ ~ - 35 ℃. It is mainly used for quick freezing of food, medicine and chemical raw materials. What is the function of quick freezing cold storage construction? Cryopreservation is designed to reduce the temperature of cryopreservation and cryopreservation. In short, the function of the construction of low-temperature quick-frozen storehouse is to quickly freeze the stored goods and resist a series of reactions. What are the characteristics of the construction of quick freezing cold storage? 1. Using the most advanced refrigeration technology and insulation board manufacturing technology. 2. Perfect engineering design, advanced production technology, strict quality assurance management, to ensure that the products in every production link are layer by layer, so that users to

  • Construction of double temperature cold storage

    The construction of double temperature cold storage is to divide a set of cold storage into two single rooms with different temperatures by adding a partition board, and install two sets of warehouse doors respectively. According to the needs of food storage, different temperatures are designed to achieve the functions of preservation and refrigeration at the same time. The refrigeration unit uses one centralized cooling unit, and two sets of evaporator in the warehouse are used for refrigeration at the same time. The temperature control system can display and control the temperature of each room independently. Because one machine double control system is used to control the temperature of two rooms, when the temperature of one room meets the set requirements, the control system will turn off the refrigeration in this room, and the refrigeration unit will not stop working until the temperature of the other room also meets the set requirements. The automatic control system will control the refrigeration unit to realize the refrigeration in which room before starting the machine. 1、 The design temperature of double temperature cold storage is: 1, (0 ℃~ + 8 ℃) 2

  • Construction of pharmaceutical cold storage

    Medical cold storage is also called medical cold storage. Pharmaceutical cold storage is mainly used to store all kinds of pharmaceutical products that can not be guaranteed under normal temperature conditions. Under the condition of low temperature (storage temperature is generally - 5 ℃ ~ 8 ℃), the pharmaceutical products will not deteriorate and lose efficacy, and the shelf life can be extended. The medicine cold storage can be divided into: vaccine cold storage, blood cold storage, medicine cool storage, biological reagent cold storage and so on. Vaccine cold storage design features 1. The insulation board of vaccine cold storage adopts polyurethane double-sided color steel plate.
