A Verderflex Smart unit was recently installed at Mother Earth Brewing (MEB) in Kinston, NC, through US distributors VerderGPM, in an effort to minimise labour costs and improve the yeast’s quality.

MEB had been using pressure tanks to transfer its yeast harvest, which was a lengthy process, costly due to the CO2 and inconsistent in maintaining the yeast’s quality.

Additionally, this process of transferring yeast had a very complicated set-up procedure.

The yeast is transferred from a vat into a keg for storage and cooled to be dosed into another batch that, under the brewer’s current system, required several coordinated valves opening and closing to ensure the proper vessels were pressurised, then relying on the pressurised vessels to perform the harvest.

After discussing its application parameters and the advantages of a peristaltic pump to simplify the process, MEB purchased a Smart S30 Model B with 15.9 x 3.2mm Verderprene tubing.

As a result, its transfer time for the yeast harvest was cut from three hours to one and the yeast quality was improved due to the ability of the Smart pump to safely and gently handle shear-sensitive materials.

Josh Brewer, brewmaster for MEB said he purchased the Verderflex Smart Pump in an effort to minimise the labour costs associated with the long process of harvesting yeast and to improve the quality of the harvest.

He added that the Verderflex Smart Pump is helping the company to save money and increase output to meet demand, all while maintaining exceptional yeast-handling sanitation.

Easily repeatable procedures over time have resulted in a reduction in man hours for the yeast harvest, which can now be dedicated to other responsibilities.

In addition, there are fewer hours required for set-up time as well as clean-up, as the tubing is the only thing to come in contact with the pumped fluid and can be replaced in a matter of minutes.

According to Verderflex, this correlates to greater profit from increased efficiency.

Verderflex® peristaltic hose pumps and tube pumps are the ideal solution for pumping liquids and dosing chemicals. Ranging from smaller Original Equipment Manufacture (OEM) pumps to the world’s largest hose pumps used in very heavy industrial applications.

Verderflex® peristaltic hose and tube pumps are used in many industries including: water and wastewater, mining, food & beverage, chemical, pharmaceutical, printing and packaging.

Verder’s peristaltic tube and hose pumps can pump abrasive, highly corrosive, viscous, high density and shear sensitive products.
