Essential Guide to Safe Operation and Maintenance of Multifunctional Extraction Tank

1.Equipment Overview
The multifunctional extraction tank is specially designed for extraction of traditional Chinese medicine and other plants. It has direct and indirect heating functions, is corrosion-resistant and easy to operate. It is suitable for extraction with solvents such as water and ethanol, and has the characteristics of high efficiency, energy saving and safety.

2.Equipment Configuration
Main structure:

Usually a straight cylinder design, it can be made into a positive cone, mushroom shape, etc. according to the size limit of the installation space.

Four-ear hanging support to ensure the stability of the equipment.

The upper head is equipped with a feeding port for easy feeding operation.

The bottom adopts a pneumatic slag discharge door, equipped with a cylinder and a safety interlock device to ensure safe operation.

Material selection:

The extraction tank is made of stainless steel SUS304/SUS316L (or other special materials) to ensure corrosion resistance and product quality.

Customization range:

Volume range: 0.05m³-10m³ to meet different production needs.

Design pressure: Generally designed as normal pressure in the tank, jacket 0.35MPa; cylinder working pressure is 0.7MPa.

Insulation and heat insulation:

The insulation layer material is generally made of aluminum silicate wool with a thickness of δ=50mm to reduce heat loss.

Optional accessories:

Multi-pass tube condenser, cooler, oil-water separator, delivery pump, filter, etc. can be selected to improve extraction efficiency and product quality.

3.Safe operation

Preparation before operation:

Make sure that the operator has received professional training and understands the equipment operating procedures and safety precautions.

Check whether all parts of the equipment, especially safety accessories (such as safety valves, pressure reducing valves, pressure gauges) are intact and in normal condition.

Operation process:

Strictly follow the operating procedures for feeding, heating, extraction and slag discharge to ensure standardized operation.

Monitor key parameters such as equipment pressure and temperature to ensure operation within a safe range.

Check the equipment sealing regularly to ensure no leakage.

Valve operation:

Valve operation should be accurate and quick to avoid equipment failure or safety accidents caused by misoperation.

When opening or closing the valve, ensure that the valve is fully open or closed to avoid leakage or pressure fluctuations caused by partial opening.

Emergency handling:

In case of equipment abnormality, leakage or other emergency situations, the emergency stop button should be pressed immediately to cut off the power supply and gas supply.

Take appropriate emergency measures quickly, such as evacuating personnel, reporting to superiors, etc.

4.Maintenance and care

Lubrication and cleaning:

Keep the moving parts of the equipment lubricated and clean to ensure the normal operation of the equipment.

Clean the surface of the equipment regularly to prevent dirt and corrosion.

Replacement of seals:

When the seal is found to be invalid or damaged, it should be replaced with a new seal in time to ensure good sealing of the equipment.

Insulation layer maintenance:

Regularly check whether the insulation layer is intact. If it is damaged, it should be repaired or replaced in time.

Daily inspection:

Periodically conduct a comprehensive inspection of the equipment, including key components such as electrical systems, piping systems, and valves.

Record the operation status and inspection results of the equipment to promptly discover and deal with potential problems.

5.Summary

The multifunctional extraction tank is an important equipment for the extraction of traditional Chinese medicine and other plants. Its reasonable configuration, safe operation and regular maintenance are the key to ensure the stable operation of the equipment and improve production efficiency. Operators should strictly abide by the operating procedures, conduct regular inspections and maintenance, and ensure the safety and reliability of the equipment.
