Moreover, the site factor of civil cold storage is very important and will have a great impact on the cost. If a fixed price is given directly, it will only save costs, cut corners and fail to guarantee the quality and safety of cold storage. Cold storage is generally calculated according to the following calculation method:
First of all, technicians need to calculate and evaluate the design scheme and drawings after on-site investigation according to the requirements of customers. Fees usually include the following aspects:
1, library fee
Such as polyurethane board, beam/column reinforcement, top and bottom, etc.
If some surfaces need structures such as foundation concrete, one party shall be responsible according to the specific situation.

Fresh-keeping and cold storage of vegetables is a way to inhibit the activity of microorganisms and enzymes and prolong the long-term storage of vegetables.
Cold storage technology is the main way to keep modern vegetables fresh at low temperature.
The fresh-keeping temperature range of vegetables is 0℃ ~ 65438 05℃. Fresh-keeping storage can reduce the incidence of pathogenic bacteria and the decay rate of fruits, and also slow down the respiratory and metabolic processes of vegetables, thus achieving the purpose of preventing decay and prolonging storage period.
