Small Vertical Retort with Hydraulic Automatic Open & Close Door for Wood Products & Herb Products


Product Description:


Vertical Retort with Hydraulic Pressure Retort Open & Close Door for Woods is designed to sterilize rarous wood products, such as logs, wood flakes, wood plates, wood sticks, and so on.

The wood products are placed into the Load Container ( Sterilization Baskets / Sterilization Plates / Sterilization Trays / Sterilization Bucketes), and the Load Container will be pushed and fixed firmly in the Pressure Vessel, to avoid any damage during sterilization process. 


Application Range for Vertical Retort:

All the wood products:

Logs, wood flakes, wood sticks, wood plates etc.

And various Herb Products


Wood Plate

Wood Stick

Wood Block

Wood Flake

Herb Products

One Completed Sterilization Process Cycle:

There are 3 Phases during one completed sterilization process cycle:

1. Heating Phase T1: (Also called Heating-up Stage)

    The Heating Phase is the first phase. It starts from the High Temperature & High Pressure

    steam(approx. 0.80MPa) injected into the pressure vessel, until the temperature of        

    sterilization water finally reachs the pre-set Sterilization Temperature.

    As per the general rules, the international standard Sterilization Temperature is appox. 170

   ℃, which is suitable for most of wood products & herb products.

2. Sterilization Phase T2: (Also called Holding Stage)

    After Heating Phase finish, and the temperature reach to 170 ℃, the Sterilization Phase will

    begin. During this phase, the steam will be stop, and the 170 ℃ will be kept for a pre-set

    period of time, and finally achieve the effection of Commercial Sterility. Meahwile, the

    steam will also be injected, to increase the pressure in the vessel to approx. 0.80MPa.

    Generally speaking, for regular wood products & herb products, Holding Phase will be

    aprrox. 20~25 minutes. But, it is also effected by many actual factors, such as the materials,

    size, thickness, hardness, density etc. characters of various products.

3. Release Phase T3
    After Sterilization Phase finish, the Release Phase will be started automatically at once, the  

    Pressure Release Valve will be opened and kept opening condition automatically by control

    system, till to all the pressure in the pressure vessels are totally released.
   After all the pressure in the pressure vessels are totally released, the control system will

   offer a warn alarm, and then the operator can open the Interlock Devices manually, and

   touch the “Open” key in the PLC Touch Screen, the doors will be openly automatically.
   This Release Phase is very fast, and will take approx. 4~5 minutes to release all the pressure

    in the pressure vessels totally.

The above are to explain the Operational Principle of Vertical Sterilization Autoclave. In practice, all the phases will be hanlded by Control System automaticly, it's easy to operate. 


Both the Sterilization Temperature & Sterilization Pressure can be designed and manufactured,  freely based on different requirements for different client's Products.
