Heating the mushroom hall
In mushroom halls, two factors cause heat production; One is heat transfer through the walls and roof, which is prevented by proper insulation, and the other is heat generation through the substrate due to the growth and respiration of mycelium and mushroom growth in different stages of cultivation and CO2 produced, which itself will increase the temperature. Three temperatures are important in the mushroom production process: the temperature outside the breeding hall, the temperature inside the breeding hall and the temperature of the growth bed.
In the article "How to cool mushroom growing halls?" The methods of cooling the mushroom hall were discussed, in this article we discuss the methods of heating the mushroom growing halls.
Different heating systems can be used for mushroom growing halls, including:
1- Heating devices that include all types of boilers.
By producing hot steam in mushroom cultivation halls, boilers control the two factors of humidity and temperature. In addition to providing heat, boilers are also used for the kokat process (disinfection of breeding halls) and pasteurization of cover soil. In more heating systems, there is no problem of creating dry air and the dispersion and diffusion of heat is very pleasant. One of the disadvantages of the heating system is its high energy and startup costs.
2- Dry heating systems that include electric heaters or heaters and hot water heaters.
Heaters are used for home salons and produce heat and ventilation. Heaters are divided into three categories: electric heaters, heater jets and cabinet heaters.
Hot water heaters increase the temperature of the hall due to the production of hot and dry air, and their use is not recommended.
There are several problems with the use of a heater. First, the oxygen from the environment is taken, and secondly, the heat generated by the heater is dry and takes away the humidity of the room (we know that humidity is very important in the discussion of mushroom cultivation). Thirdly, using heaters is possible. is to produce CO2 gas, which is said to lead to diseases such as ringworm.
If you have to use a heater, try to generate the heat in another room and transfer it into the room with a channel, that is, make the air necessary for the room in a small room and then transfer it into the mushroom cultivation room with a duct.
3- Using hot pipes along the walls and on the sides of the growing room
In this method, the air inside the hall may be dry, but the cost of setting it up is low.
4- Warm air conditioning system + heater
In this method, all the incoming air passes through the heater section and the cost of electricity will be high. It is possible for the air in the hall to dry out, which needs to be humidified, but inside the hall, it is possible to create completely uniform conditions.
