Product Introduction 
The hydropulper uses a high-speed rotor to generate intense hydraulic shear forces, rapidly disintegrating and dispersing fibrous raw materials in an aqueous medium. It is equipped with a variable-speed motor and a gear-belt drive system for smooth, reliable operation. Permanently lubricated bronze bearings ensure maintenance-free running. The silicone resin heating jacket, combined with a J-type thermocouple and digital controller, allows precise temperature regulation for constant-temperature pulping. The 316 stainless steel vessel and discharge valve offer excellent corrosion resistance and ease of cleaning, suitable for sample processing in various chemical environments.

Key Features 
High Pulping Capacity Maximum capacity of 600 g bone-dry pulp; at 15% consistency, pulps no less than 350 g of bone-dry fiber, meeting high-throughput lab requirements.
Wide Variable Speed Range 0-800 rpm stepless speed control with bright LED digital display, allowing flexible setting based on fiber type and defibering needs.
High Consistency Adaptability Pulping consistency from 5% to 35%, suitable for both virgin and secondary fibers with broad applicability.
Constant Temperature System 800 W silicone resin heating jacket with J-type thermocouple and digital controller; adjustable from ambient to 80°C for precise constant-temperature pulping.
316 Stainless Steel Construction The vessel and 1½" discharge valve are both made of 316 stainless steel for superior corrosion resistance, easy cleaning, and cross-contamination prevention.
Compact Benchtop Design Overall dimensions only 700×500×1200 mm; small footprint and light weight save valuable lab space and facilitate relocation.
Maintenance-Free Drive System Variable-speed motor with gear-belt and pulley drive; permanently lubricated bronze bearings ensure smooth, maintenance-free operation.
Versatile Application Range Suitable for superfine grinding of Chinese and Western medicines, pearls, chemical raw materials, food ingredients, minerals, soil, grain, coal, and other experimental materials.

Main Technical Specifications

FAQ 
1. What types of fibers can be processed in the hydropulper?
It is suitable for virgin fibers such as wood pulp, cotton pulp, and hemp pulp, as well as secondary fibers like waste paper and paperboard. By adjusting speed and consistency, it can process fibers of different lengths and strengths.

2. Is the heating jacket mandatory for every use?
The heating jacket is optional. It helps maintain a constant temperature during pulping, accelerating fiber swelling and defibering, especially for high-consistency or heat-requiring processes. You can choose whether to activate it based on experimental needs.

3. How do I clean the equipment to prevent fiber residue and cross-contamination?
After pulping, open the 316 stainless steel discharge valve to drain the pulp, then rinse the vessel interior with clean water. The smooth 316 stainless steel surface resists adhesion; wipe with a soft cloth after rinsing. Periodically inspect the gap between vessel and rotor for thorough cleaning.

4. How should speed and consistency be set for optimal results?
Speed and consistency depend on the fiber type and required degree of defibering. It is recommended to start at low speed and gradually increase. Consistency can be adjusted between 5% and 35% based on pulp type. Optimal parameters can be determined through small-scale trials.

5. Is the operating noise high? Does it require special installation?
The gear-belt and pulley drive with permanently lubricated bearings ensures smooth, low-noise operation. The benchtop design requires no special foundation; simply place it on a flat, sturdy workbench.

6. What size is the discharge valve? Is it easy to maintain?
The discharge valve is a 316 stainless steel 1½" ball valve with a large bore for rapid, clog-free draining. The valve body is detachable for easy cleaning and maintenance, ensuring leak-free long-term operation.
