The mushroom dryer is a kind of equipment used to dry mushrooms, and its working principle mainly relies on the heating effect of the heat source. The heat source used in the mushroom dryer and how it works will be described in detail below.
1. Heat source. The main heat sources used in the mushroom dryer are as follows:
1.Gas heat source: Gas combustion is used to generate heat, which is transferred to the air through a heat exchanger, and then the hot air is blown by a fan towards the mushrooms.
2.Electric heat source: Use an electric heating pipe or heating wire to heat the air, and then the hot air is blown by a fan towards the mushrooms.
3.Steam heat source: The steam boiler is used to generate steam, and the steam is transported to the mushroom mushroom dryer through the steam pipeline, and the steam is in direct contact with the mushroom to achieve drying.
Second, the working principle.
The working principle of the mushroom dryer mainly includes the following steps:
1.Preheating: The mushrooms need to be preheated before starting drying. Preheating allows the surface of the mushroom to evaporate water, while allowing the cells inside the mushroom to absorb sufficient water, thus maintaining its freshness.
2.Drying: After the preheating is completed, put the mushrooms in the mushroom dryer and turn on the heat source for drying. During the drying process, hot air is continuously blown to the mushroom through a fan, so that the moisture on the surface of the mushroom evaporates. At the same time, the cells inside the mushroom also absorb heat, causing water to evaporate from the inside to the outside.
3.Moisture drainage: During the drying process, a large amount of moisture is generated. In order to keep the mushroom dry, it is necessary to expel the moisture in time. The dehumidification system is generally composed of a dehumidification outlet and a dehumidification fan, the dehumidification outlet is set at the bottom or side of the mushroom dryer, and the dehumidification fan continuously discharges moisture out of the machine.
4.Cooling: After drying, the mushrooms need to be cooled. Cooling prevents mushrooms from cooling too quickly and causing moisture to recur. The cooling system generally consists of a cold air inlet and a cold air outlet, the cold air enters the mushroom dryer from the inlet, mixes with the hot air and discharges out of the machine from the outlet.
5.Collection: After the cooldown is complete, the mushrooms need to be collected. The collection system generally consists of a collection opening, which is placed at the bottom or side of the mushroom dryer, and a collection box is placed below the collection port to store the dried mushrooms.
The working principle of the mushroom dryer mainly depends on the heating effect of the heat source and the dehumidification effect of the dehumidification system. Through the steps of preheating, drying, dehumidification, cooling and collection, the mushroom mushrooms can be dried quickly, evenly and efficiently. At the same time, in order to ensure the quality and efficiency of drying, it is also necessary to pay attention to the control of temperature, humidity, wind speed and other parameters of the heat source, and clean and maintain the equipment in time.
