Ltd. is located in Qingdao, Shandong Province, which is the largest production base of the world's largest edible fungus factory company--Shandong Certain Biological Company at present. The project consists of a mushroom stick production center with a daily output of 180,000 sticks and 300 modernized mushroom-producing greenhouses, which is the world's largest edible fungus factory production base at present, and also the edible fungus The benchmark factory of factoryization.

China's edible mushroom production currently relies mainly on farmers' traditional planting methods, which are labor-intensive, long cycle, dependent on the natural environment, and unable to achieve annual production.
A biotechnology company in Shandong has made great progress in mushroom factory production in recent years. Before the completion of the base in Qingdao, a preliminary breakthrough in edible mushroom factory production has been achieved in several small bases. It requires more precise control of parameters such as temperature, humidity, CO2 concentration, etc., as well as higher quality and yield of edible mushrooms, and energy consumption per unit of production is required to be reduced by more than 10% compared with the previous base.
Since a factory in Qingdao aims to be a smart factory, it has higher requirements for automation and intelligence, and such a huge factory requires all air-conditioning equipments to run automatically, which reduces the difficulty of equipment management personnel and management.
In order to meet the needs of the project, a redesign of the program for the project was provided for comparison with the original program.
Divide the whole project into 5 blocks, including 4 blocks of mushroom sheds and 1 block of mushroom stick production center.
We use Qingfeng wide frequency inverter magnetic levitation chiller and low ring temperature air-cooled heat pump module. These units provide stable cooling and heating to ensure that the temperature and humidity in the mushrooming area are precisely controlled.
We provided the warehouse intelligent control system, computer room group control system and remote monitoring system for the whole project. These systems are capable of realizing intelligent control and monitoring of temperature, humidity, CO2 concentration and other parameters.
We derived a uniform airflow organization scheme through CFD simulation to ensure uniform air flow in the mushrooming area and provide suitable environmental conditions.
Advantages of unit application:
1. The project adopts the central control cooling and heating mode, which improves the quality of edible mushrooms by simulating the optimal growth environment required by edible mushrooms (including temperature, humidity, CO2 concentration and light), realizes year-round production and avoids the disadvantage of traditional mode of “relying on the sky to eat”.
2. The entire project covers an area of about 350 acres of mushroom sheds, will be divided into four blocks independently of the centralized control of refrigeration, and the machine room is basically located in the middle of each block, can effectively shorten the overall cost of the project pipeline to reduce the initial investment, while greatly reducing the head of the pump to reduce the operating costs of the system;
3. The project adopts Qingfeng frequency conversion magnetic levitation chiller as the refrigeration host, whose power accounts for 50%-60% of the whole system, the unit has a number of advantages;
4. The growth of edible fungi has requirements for the temperature, humidity, CO2 concentration, light and pergola of the greenhouse. At the same time, different growth stages of temperature, light and humidity parameters of different control points. Qingfeng intelligent control system for edible fungus can meet the demand for automatic adjustment of parameters at different growth stages of edible fungus, without the need for personnel to adjust the set parameters back and forth. This realizes the standard of automated intelligent production of edible fungus factory, improves the efficiency, reduces the equipment regulating personnel and lowers the labor cost. In addition, the control system has corresponding measures in energy saving, making full use of the outdoor temperature to save energy and reduce consumption, and has a data storage function.
5. The project is equipped with a remote monitoring system, which can monitor the parameters of each room via PC or cell phone and realize remote adjustment when necessary. At the same time, alarm information will be pushed to the designated personnel in time when there is a fault in the on-site room, which improves the response time for troubleshooting and guarantees the safe growth of edible mushrooms. For rooms with the same function, only the parameters of one of them need to be set, and the parameter setting of all rooms can be realized through the one-key override function, thus reducing the operation time of the regulators, improving the work efficiency and reducing the labor cost.
