Food cold storage installation construction
We have four seasons of a year are now able to eat any food such as fruits and vegetables to eat, how this is going on, some food is not all year roundthere will be, these are dependent on food cold storage to storage, therefore,can eat to want to eat the food we have four seasons of a year. This demand has increased demand food cold storage, we need to build a lot of food cold storage, how to build a number of food storage.
Food storage is used in food freezing and cold storage buildings, it is through the method of artificial refrigeration, make the library to maintain a certaintemperature. In order to reduce the introduction of outside heat, cold floor,walls and roof are laying a certain thickness of dampproof layer and insulatinglayer, in the food cold storage engineering management, should be based on the characteristics of food cold storage, the implementation of scientific management, to ensure safe production, prolong the service life, reduce the production cost, save repair costs, improve the economic benefits of the enterprise purpose.
Cold storage building must choose a reasonable location, the choice of location more convenient place, convenient storage of goods is also removed.Cold storage building from the beginning of construction to the equipment installation is usually performed at room temperature, the structure system is in a normal state; and the cold storage after put into use, the system structure is in low temperature environment. Due to the structure system of large temperature difference and deformation caused by the much larger than ordinary construction, so it must be the calculation of stress and temperature,to prevent to produce "cold bridge". Floor should take measures to preventfreezing, Keelung and building damage caused by. At the same time should choose strong freeze resistance material, in order to strengthen the structure of the freeze resistance, durability.
Plane layout of food cold storage should make reasonable technological process, short lines, do not cross, high and low temperature zoning clear, try to narrow the retaining structure of the area, the distribution of column netneatly, and considered to facilitate the expansion and maintenance. Thegeneral plane into a square, multilayer cold storage is often built dumbbell type or single type. Dumbbell type will be high temperature storage and low temperature library is divided into two envelope independent body, in the middle of the hall of convergence, better use effect. Single type in high and low temperature reservoir with adiabatic wall to floor and ground separated, doorsand room temperature hall is connected with the air door, set the scene, in order to prevent the cool air in the storage overflow.
Food cold storage buildings to prevent the penetration of water vapor diffusionand air. Outdoor air intrusion increase consumption not only cold food cold storage, but also to the warehouse to moisture, moisture condensation frombuilding especially insulation structure damp freezing damage, so to set up athermal insulation layer, the food cold storage building has a sealing and antisurge vapour with good performance.
Effects of food cold storage foundation by low temperature, the moisture in the soil is easy to be frozen. Because the soil freezing after volume expansion, will be deformation caused by ground rupture and the entire building structure,serious will make food storage can not be used. Therefore, cold food cold storage floor in addition to the heat insulation layer outside the heat insulationlayer effectively, also must be treated to prevent soil freezing.
Floor food cold storage to pile up a lot of goods, but also pass varioushandling machinery and equipment, flat top is also provided with a refrigeration equipment or pipeline. Therefore, its structure should be strong and relatively high bearing capacity.
