Efficient Mixing Equipment for Edible Mushroom Cultivation

Mushroom Substrate Mixer is an essential piece of equipment for edible mushroom production, designed to evenly mix raw materials, water, and nutritional additives before bag filling and sterilization. With a durable mixing structure, adjustable operation time, and efficient blending performance, it solves common problems in mushroom cultivation such as uneven moisture distribution, inconsistent substrate quality, and high labor costs caused by manual mixing.

The machine adopts a horizontal mixing structure with strong mixing blades, ensuring that materials such as sawdust, corn cob, straw, and other agricultural residues can be fully mixed with water and additives. It is widely used in commercial mushroom farms, substrate preparation workshops, and automated mushroom production lines.

Key Specifications of Mushroom Substrate Mixer

Different production scales require different mixing capacities. The following three models are commonly used in edible mushroom substrate preparation.

Model

Equipment Type

Main Specifications

Features

MIXH200A

Flip-type Substrate Mixer

Power: 4kw / 380V

Capacity: 200kg/batch

Weight: 380kg

Dimension: 2750×900×1100mm

Uses a horizontal double-shaft structure. Materials are fully placed into the mixing chamber, then sprayed with water during mixing. Equipped with safety locking device and automatic turning function. Mixing time can be adjusted according to raw materials. Equipped with wheels for easy movement.

MIXH300A

Side Discharge Substrate Mixer

Maximum Capacity: 300kg/batch / 8min

Suitable Materials: Corn cob, sawdust, etc.

Power: 4kw

Voltage: 380V 50Hz

Weight: 480kg

Dimension: 2290×880×1160mm

Uses motor and reducer structure to effectively reduce speed and increase torque. Spiral mixing blades provide strong wear resistance and uniform mixing. Laser-cut components improve processing accuracy. Side discharge design makes unloading cleaner and reduces cleaning time.

MIXH800A

Side Discharge Substrate Mixer

Mixing Capacity: 0.8m³

Power: 4kw

Reducer Drive System

Weight: 0.58T

Dimension: 2290×1080×1191mm

Capacity: 500kg/batch / 15min

Designed for larger production requirements. Strong mixing capability, stable operation, and convenient movement with directional wheels. Suitable for continuous substrate preparation in medium and large mushroom factories.

 

Working Principle: How Mushroom Substrate Mixer Works

The mushroom substrate mixer completes the preparation process through several steps:
01

Raw Material Feeding

Before mixing, mushroom cultivation materials are prepared according to the formula, including:

Sawdust

Corn cob

Straw

Cottonseed hull

Agricultural waste materials

Nutritional additives

The materials are loaded into the mixing chamber manually or through an automatic feeding system.

02

Mechanical Mixing Process

After starting the machine, the motor drives the reducer and mixing shaft. The spiral blades rotate continuously to lift, turn, and move the materials.

The mixing process helps:

Break material blocks

Distribute nutrients evenly

Improve substrate structure

Increase moisture uniformity

03

Water and Additive Mixing

During operation, water or nutrient solutions can be sprayed into the mixing chamber.

The double-shaft or spiral mixing structure ensures:

Even moisture distribution

No dry areas inside substrate

Stable substrate quality

04

Discharge and Next Production Stage

After reaching the preset mixing time, the finished substrate is discharged through the outlet.

The prepared substrate can then enter:
Substrate Filling → Sterilization → Cooling → Inoculation → Cultivation

Suitable Raw Materials and Mushroom Applications

Suitable Raw Materials

Mushroom substrate mixers are designed for various edible mushroom cultivation materials.
Sawdust
Corn cob
Rice straw
Wheat straw
