The pulp manufacturing processes are roughly classified under three categories: timber cut-up, pulping and refining. Among these, the pulping process is the most important. According to the pulping method, produced pulp is classified as DP, KP, SP, SCP, GP or MP. Among these, the KP type is the most commonly used in paper manufacturing, and is produced in the greatest volume, preferred because of its quality and cost advantages. Unlike the GP or MP method using mechanical shearing force, the KP method mainly resorts to chemical treatment using a chemical agent (mix liquid of sodium hydrate and sodium sulfide solutions). Autoclaves are used in the pulping process for testing and studying digestion of various wood chips and yield measurement as well as bleaching/deinking of used paper, collection of chemicals and treatment of waste cooking liquid. This autoclave is easy to handle since the chamber and lid are made of stainless steel that can resist chemical corrosion even after long years of service.

This autoclave is for timber chip cooking tests in a university laboratory, etc. As such, the cooking chamber is small-sized and can be heated on a gas burner, which is suited for a simple pulping experiment. By removing the fixing pins supporting the chamber body, it can be shaken sideways, helping even permeation of the liquor into chips.

This autoclave is used in digestion experiments on various wood chips. In order to strictly comply with the temperature setting according to a preset cooking schedule, a thermometer device is installed on the chamber body for program-based control, enabling automatic control via the control unit. This mechanism significantly contributes to higher accuracy of digestion experiments, improved reproducibility and labor saving.

This autoclave is used in a range of chemical experiments as well as for cooking of various wood chips. It is designed to allow reactions to take place adequately and uniformly even with a very low liquid ratio, providing an advantage that allows experiments under conditions close to the site conditions. In addition, in an effort to control environmental problems, it is widely used in studies of oxygen bleaching and oxygen digestion.

This device aims to enhance safety and ease operations before and after a chip digestion test, such as preparing chips into the cooking chamber and taking them out upon completion. Chips can be fed into the chamber as it is erected. After cooking, the lid is removed and the autoclave is inverted using the handle for easy retrieval of digested pulp.

Like the horizontal type rotating autoclave, this cooker also performs efficient cooking tests on various types of chips. Its advantage lies in that the chamber body rotates slowly in a vertical direction, achieving quick and even permeation of the cooking liquid into chips. It consists of a chamber, rotating system and electric heater. The chamber is provided with a pressure gauge, safety valve, thermal sensor, needle valve, etc. Temperature is automatically controlled.
