The seafood machine can be customized according to customer requirements; Many fruit wholesalers will transform the original warehouse into a fruit preservation warehouse in order to store fruits for a longer time. Due to the huge difference between warehouses， it needs a lot of attention to transform the warehouse into a qualified energy-saving fruit preservation warehouse.
It is equipped with temperature compensation to automatically adjust the water temperature. The water temperature of ultrasonic atomization is - degrees. If our humidifier is connected with the warehouse， there is no temperature compensation， even in the work， the water temperature is low
Installation materialsPolyurethane refrigeration board uses light polyurethane as the internal material of refrigeration board. The advantage of polyurethane is very good heat insulation. The exterior of the cold storage is composed of SII， PVC color steel plate and stainless steel plate. The advantage of this is that it can prevent refrigeration because the temperature difference inside and outside the board is large， and the temperature will disperse， which makes refrigeration more energy-saving and improves the working efficiency of refrigeration.
Cold storage is fireproof， flame retardant and high resistance. Professional cold storage installation， cold storage installation， cold storage construction， fruit preservation cold storage， medical cold storage and other special products old brands， price advantages and guaranteed quality. Polyurethane is a flame retardant self extinguishing material after adding flame retardant. Its softening point can be above degrees Celsius and will only be decomposed at higher temperatures. In addition， the ash formed on the surface of polyurethane will be in its foam， and this ash will help isolate the foam below. It can effectively prevent the spread of fire. Moreover， polyurethane will not produce harmful gas at high temperature.
The selection of cold storage is very important for cold storage， because cold storage is different from ordinary cold storage. The temperature in cold storage is usually low， and the air temperature， humidity and environmental requirements are relatively high. When selecting cold storage， attention must be paid to the selection of cold storage with better temperature. If the selection of cold storage is not good， which is easy to cause the deterioration of products in the cold storage， or the refrigeration compressor in the cold storage often works， wasting more resources and increasing the cost.
The exhaust temperature of the compressor equipment is often. When the season changes and the temperature difference changes greatly， pay attention to it. If the machine is abnormal， it needs to be checked in time.
Honest managementStep of cold storage design: selection and laying of cold storage thermal insulation materials. The use of cold storage thermal insulation materials must be adjusted to the time， which not only has excellent fire resistance， but also has high cost performance. There are several types of cold storage insulation materials. One is the plate produced and processed into a fixed shape and specification， with fixed length， total width and thickness. The cold storage plate with relative specification and model can be selected according to the installation of the warehouse body. The high and medium temperature cold storage generally adopts cm thick cold storage plate， cm or cm thick cold storage board is generally used for ultra-low temperature cold storage and freeze-cleaning cold storage; Another kind of cold storage can be sprayed with polyurethane spray paint and polyurethane foam， and the raw materials can be sprayed into the brick or concrete warehouse of the cold storage to be built immediately. After shaping， it is both waterproof and thermal insulation. Thermal insulation materials include polyurethane， polystyrene grease， etc. Polyurethane is non hygroscopic and has good fire resistance， but the cost is high; Polystyrene resin has strong water absorption capacity and weak fire resistance， but the cost is low.
Ammonia filling leak test: ammonia filling leak detection can be carried out after system blowdown and pressure leak test. The purpose is to improve the air tightness of the system and lay a good foundation for the work of ammonia filling and thermal insulation materials of the system. After air leakage detection， some obvious leakage points can be found. However， due to the poor air permeability， the leakage points blocked by dirt along the tiny sand holes are not easy to be detected. Therefore， ammonia must be filled. In addition to good permeability， ammonia also has odor and is easy to be found， At the same time， phenolphthalein test paper can be used for leak detection because it is rose red in the presence of ammonia.
When the cold storage is built， it will not only increase the cold consumption of the cold storage， but also bring moisture into the warehouse. Moisture condensation will damp the heat insulation structure and freeze and damage the cold storage structure. Therefore， it is necessary to set moisture-proof and heat insulation layer， professional cold storage installation， installation of cold storage， cold storage construction， fruit fresh-keeping cold storage， which have a complete variety， and have a long service life! Products lead the wire industry. Welcome to inquire so that the cold storage building has good sealing， moisture-proof and steam isolation performance.
Gillard melenaAccording to the size and nature of the cold storage area and in combination with local regulations， the construction form of food cold storage warehouse is to determine the plane layout based on the site， whether it is a single-layer or double-layer warehouse， and the structure is the selection of steel structure or reinforcement solidification. Cold storage capacity， production process， refrigeration， product stacking， temperature， etc. are used to determine the size and location of the cold storage room， so that it can become a whole.
Able to withstand the harsh local climate and its changes. Neither high temperature nor severe cold climate will cause irreversible damage or deformation to the external insulation system. The drastic change of the surface temperature of the external wall， such as the sudden shower after a long time of exposure， or shading during exposure， will not cause damage to the surface of the cold storage.
When installing polyurethane insulation board， ensure that its surface is smooth and flat without scratch and warpage.
