Profit Estimation
For example, based on storage capacity for 1,000 tons of fruits and vegetables.
(1) Process design and equipment with computerized automatic control systems, air doors, several fans, and water storage tanks.
(2) Construction engineering protective structures are similar to general cold storage, available in underground or above-ground styles. They can be divided into storage rooms with different storage conditions according to customer requirements. The storage warehouse (length x width x height) measures 40m x 30m x 14m, the control room is 20 cubic meters, and the loading/unloading shed is 80 cubic meters.
(3) The estimated total investment is 3.97 million yuan, including 2.19 million yuan for fixed assets, 180,000 yuan for other construction costs, and 1.6 million yuan for working capital. 70% of the investment is allocated in the current year, with 30% in the second year.
(4) The estimated economic benefits include a cost estimate of 925,400 yuan, with a food cold storage facility costing 700,000 yuan for vegetables, fruits, and other raw materials, 30,000 yuan for energy consumption, and 324,000 yuan for annual labor wages. The annual sales revenue is 1,800,000 yuan, with a 46.4% increase in output value per 100 yuan of investment, a 36.9% investment benefit rate, a payback period of 2.71 years, and an input-output ratio of 1:11.2.
Layout of a small cold storage
The layout of a small cold storage facility typically consists of a single-story building, mostly on the ground floor and basement, with limited space. Installation of quick-freezing and refrigeration storage, and storage of products is not extensive. Therefore, in the design of the layout, the size of the cold storage doors, the need for insulating materials, and the selection of other cold storage equipment are designed based on these characteristics.
Small cold storage height
Net height of small cold storage (i.e., the height from the ground to the top of the storage), refrigerated warehouse facility, usually about 20 cm lower than the building height, the net height of the cold storage is generally between 2 to 3 meters, depending on the height of the warehouse, the amount of goods to be stored, and the convenience of picking and delivering.
Key Points of Refrigerated Cold Storage Technology
① The cold source within the warehouse comes from ice water, providing stable low temperatures, high humidity, good preservation quality, and extended shelf life.
② No refrigeration equipment required; just a few fans, low investment, and minimal maintenance costs. Compared to mechanical refrigeration warehouses that typically use chlorofluorocarbons or ammonia, energy savings are over 90% and there is no pollution.
③Suitable for building storage facilities in regions with an average annual temperature below 13°C and winter temperatures below -8°C; Guangdong cold storage, the lower the temperature, the better the effect.
④High level of automation, easy management.
Above is an introduction to the characteristics of fruit cold storage. As for the cost of a fruit preservation cold storage, if it's built in Shanghai, a 30-cubic-meter storage (about 10 square meters) would cost around 25,000-40,000 yuan, while a 100-square-meter storage would be approximately 100,000-160,000 yuan. The quoted prices are for reference only, as the costs vary depending on the size and configuration of each cold storage facility.
