M/K ASME & CE Certified Laboratory Pulp Digesters
The Most Precise Laboratory Digesters Available
M/K Systems Inc. offers the most precise laboratory pulp digesters available. Each system has a patented liquor mixing module, an anti-turbulent tubing design, and high-speed pumps give you the best liquor/chip interaction available. We have options that allow you to easily and safely inject additives during your cook. Rent or purchase our high-pressure pulp digesters for all of your cooking needs. The digester is easy to use, safe, and reliable. Use our systems for kraft cooks, sulfite cooks, bleaching, cooking with additives, etc. Other materials customers investigate include Arundo Donax, industrial hemp,
and hop residuals in kraft cooks,
as well as low temperature organosolv pulpin M/K digesters employ our patented deisgns (patent #s US 7, 811, 416 and US 8, 172, 984. Other patents are pending).
What Makes Our Product Stand Out
Our patented technology employs a liquor circulating system with both liquor and vapor sensors, triple insulation, excellent system temperature control, and many other redundant safety features. No other digester can match our device’s precison. Our patented liquor module optimizes chip-liquor interactions.
With the M/K Digester you will obtain precise cooking results. As of 2019, our 20-liter vessel systems heat to 175°C from room temperature within 40 minutes, whether you are cooking by H-factor or traditional temperature/time segments.
Additionally, the liquor temperature control is typically +/ 0.1°C for our modern systems. Our latest rapid cooling technology cools quickly enough so that operators can run several cooking cycles per day. Each M/K Digester includes a sampling condenser for extracting black liquor at high temperatures.
