Product Description
The ASXH100B / ASXH150B Small Sterilizer is a compact and efficient steam sterilization solution designed for edible mushroom growers, laboratories, small cultivation workshops, and research facilities. It is mainly used for sterilizing mushroom substrate bags, cultivation containers, tools, and other materials before inoculation.
Sterilization is a critical step in mushroom cultivation. If harmful microorganisms are not completely removed before inoculation, they may compete with mushroom mycelium and reduce cultivation efficiency. These small sterilizers provide stable high-temperature steam sterilization to help growers create a cleaner cultivation environment and improve mushroom production reliability.
Both models are manufactured with high-quality stainless steel, providing excellent corrosion resistance, durability, and easy cleaning. The compact structure saves installation space, making them suitable for mushroom farms with limited production areas or small-scale cultivation operations.
The sterilizers adopt a microcomputer automatic control system, allowing users to freely set sterilization temperature and time according to different materials and cultivation requirements. The digital display and touch-button operation make parameter adjustment simple and convenient.
Safety is also a key feature of the ASXH100B and ASXH150B. The machines are equipped with multiple automatic protection systems, including:
- Over-temperature protection
- Over-pressure automatic release protection
- Low-water-level protection
- Anti-dry-burning protection
After sterilization is completed, the machine automatically releases steam, stops operation, and activates a buzzer reminder, reducing operator workload and improving production safety.
With compact size, reliable performance, and easy operation, these small sterilizers are ideal equipment for mushroom growers who require efficient sterilization without investing in large industrial autoclaves.
Working Principle
Loading Materials
Before operation, mushroom substrate bags, cultivation bottles, tools, or other sterilization materials are placed into the stainless steel inner chamber or optional sterilization baskets.
The compact chamber design allows efficient loading and unloading.
Adding Water and Closing the Chamber
The required amount of water is added according to operating instructions.
After loading, the sterilization chamber door is securely closed using a bolt-type locking structure to ensure safe operation under pressure.
Heating and Steam Generation
The electric heating system heats water to generate saturated steam.
As steam enters the chamber, the internal temperature gradually increases and replaces cold air, creating a suitable sterilization environment.
Temperature and Pressure Control
The microcomputer control system automatically manages:
- Sterilization temperature
- Sterilization time
- Working pressure
Users can select sterilization temperatures between 116℃ and 134℃ according to different cultivation materials.
High-Temperature Sterilization
During the sterilization process, high-temperature steam penetrates the materials and eliminates unwanted microorganisms.
The stable temperature and pressure environment ensure:
- Uniform sterilization
- Reduced contamination risk
- Better preparation for mushroom inoculation
Automatic Steam Release and Completion
After the preset sterilization time is completed:
- The machine automatically releases steam
- Operation stops automatically
- The buzzer alerts the operator
The sterilized materials can then be removed for cooling and inoculation.
Suitable Raw Materials and Mushroom Types
They are widely used for:
Oyster Mushroom (Pleurotus ostreatus)
Suitable for small-scale bag cultivation.
Shiitake Mushroom (Lentinula edodes)
Suitable for sterilizing sawdust-based cultivation materials.
King Oyster Mushroom (Pleurotus eryngii)
Provides stable sterilization conditions for small production batches.
Black Fungus (Auricularia auricula-judae)
Suitable for small bag cultivation preparation.
Other Edible Mushroom Species
Including:
- Enoki mushroom
- Seafood mushroom
- Agrocybe mushroom
- Laboratory mushroom cultivation varieties
Capacity / Production Scale
