The buttermaking machines are intended for output ranging from 800 to 2,700 kg of butter per hour, according to the type of the machine. Their design is derived from a series of tried of the buttermaking machines type KM and ZKU, however, the design of the drives of single units is different. Revolutions of the churner are controlled by the frequency converter. Thus set up revolutions are maintained more accurately than with the originally used hydraulic power pack-noise level essentially decreased. For the drive of the separating roll and kneading machine, speed control is not done using the variable speed gearbox but frequency converters are used like for the churner. In this way, the structure of the whole buttermaking machine has been essentially simplified and consequently costs for maintenance have been reduced. All parts coming into contact with butter or cream are made of high-quality stainless steel. The buttermaking machine incorporates a system for dosing water into butter and tank for icy water with the pump. Switchboard with frequency converters is located outside the machine separately.
