Stationary gas mixing system for dairy products

Witt Gas Techniques has supplied their ISO 22000-compliant MG100 stationary gas mixing system to dairies throughout Europe to assist in the production of whipped cream, cream cheese and butter.

Witt Gas Techniques, the Warrington-based gas safety, control, mixing and analysis equipment supplier, has supplied their ISO 22000-compliant MG100 stationary gas mixing systems throughout Europe to dairies to help produce whipped cream, cream cheese, desserts and other butter products.

MG100 gas mixing systems are used to mix nitrous oxide (laughing gas) and nitrogen (25 percentN20 in N2), whilst an integrated analyser at the mixers outlet point ensures that the mixture is correct.

Nitrous Oxide is a propellant gas which is required to froth up whipped cream and other products without changing the flavour; using CO2 the product would become sour and unpalatable.

All component parts within the system, which are in contact with the gases are made of stainless steel for use within the food industry.

These systems have been designed for a variety of industrial applications, including food processing, with high flow rates and variable gas mixture requirements.

The flow capacity ranges from 0 to approx 160Nm3 per hour and they can be used with all gases except toxic and corrosive gases.

Setting accuracy is +/- 1 percent abs over a mixing range of 0-25 percent and +/-2 percent abs over a mixing range of 0-100 percent.

The mixing precision is better than +/-1 percent.

They are supplied in cabinets with a lockable transparent door.
