Company Description:

DariTech was founded in 1990 and has grown to be a top to bottom dairy service and supply company worldwide. Taking what we’ve learned in the field, DariTech’s design team has developed a diversified product line that meets the needs of today’s modern dairies. DariTech’s ability to design and manufacture DariTech’s own components lets us personally ensure the quality of each product. DariTech’s equipment is built to be durable and functional not only today, but also for years to come. DariTech’s goal is to provide every customer with a long-term value for their investment.

Technology Description:

Complete mix anaerobic digester, with external pump agitation, supported membrane roof, and external tube-in-shell heat exchangers. Designed for affordability of construction and operation, Daritech digesters can be built for the lowest cost per cow in the industry. In-house PLC control system allows for operation from a PC or smartphone, with minimal onsite personnel.  

With lower costs of construction and operations, projects can cash flow with lower revenue requirements. If nutrient recovery is the end goal, and the costs of electrical generation and interconnection are eliminated, Daritech digesters can affordably integrate with downstream nutrient capture operations.
