Milk Pasteurizer MAK Milk 100

The MAK Milk 100 pasteurizer is a batch-processing unit designed for the pasteurization of milk and similar liquid dairy products.

The device combines controlled heating with continuous mechanical agitation, ensuring uniform temperature distribution throughout the product volume. The pasteurizer features a 100-liter, double-walled stainless steel vessel. Unlike traditional pasteurizers that use a water jacket for indirect heating, the MAK Milk utilizes a combined bottom-and-air heating method. Heat generated by a 6.5 kW electric heating element (located beneath the base) is transferred to the product through the multi-layer bottom, it also serves to provide gentle, indirect air heating to the cylindrical surface of the processing vessel. This approach eliminates the need to fill, drain, and maintain water as a heat transfer medium; it reduces the risk of leaks and scale buildup. It also lowers operating costs by preventing the heat from escaping into the surrounding environment, and simplifies the overall design, thereby enhancing the unit's reliability and ease of maintenance.

The pasteurizer features an agitator drive powered by a 0.55 kW gear motor, utilizing a scraper-type mixing system. The agitator is equipped with scrapers that clean the vessel's bottom and walls, continuously moving the milk away from heated surfaces, promoting uniform heat distribution. Hinged scrapers maintain contact with the metal surfaces during operation; depending on operating conditions, they can be made out of stainless steel or polymer material.

A universal Tri-Clamp connection is used for quick and simple agitator installation without the need for any special tools, allowing different mixing attachments to be fitted to the same drive unit in just a few seconds. When producing cheese or curd, the scraper agitator can be replaced with a specialized knife for processing curd grains.

The finished product is discharged via a built-in DN50 butterfly valve, which ensures a convenient connection for transferring the product to the next stage of production.

Suitable for processing

The MAK Milk 100 pasteurizer is designed for the batch pasteurization and controlled heating of the following products:

• Milk
• Dairy products
• Liquid dairy mixes
• Products requiring controlled heating and holding
• Milk intended for further cheese or fermented milk production

Advantages

• Uniform product heating is ensured through a specialized combined bottom electric heating, and indirect heat transfer through the vessel walls.
• The absence of a water jacket or separate heat-transfer fluid system simplifies the heating system design and serves to reduce excess heat loss.
• Continuous agitation via a scraper-equipped stirrer ensures constant product movement along heated surfaces, preventing localized overheating and product adhesion.
• Scrapers on the bottom and walls enhance heat transfer by maintaining product contact with the vessel's heated surfaces.
• A universal Tri-clamp stirrer attachment system allows for the use of various attachments for different processing operations.
• A cheese curd cutting blade (optional accessory) can be installed on the same drive unit in place of the scraper stirrer, enabling the unit to process cheese curd.
• The "P" (digital) version features an automatic PID temperature control system, a holding timer, and an agitator speed controller for more precise process control.
• The "M" (manual) version features a simple six-stage heating system and provides a direct display of the product temperature.
• A DN50 butterfly valve ensures convenient and controlled product discharge.
• The double-walled stainless steel construction offers a hygienic and durable solution for professional milk processing.
• Adjustable legs allow for secure installation on various types of flooring.

Control versions

The pasteurizer is available in two control configurations.

Manual M version

The manual version is equipped with a six-step heating power selector and a bimetallic thermometer. The product temperature can be monitored directly from the front-mounted dial, providing simple and reliable control without complex electronic components.

Digital P version

The digital version provides automatic process control using a PT100 temperature probe positioned directly in the product and a PID controller. The controller automatically regulates the heating system to reach and maintain the selected product temperature. A cycle timer can be used to control the required holding period during pasteurization, while a frequency inverter allows adjustment of the agitator speed according to the product and processing requirements.

Basic equipment includes

The basic version includes a 100 L double-walled processing vessel with air insulation, 6.5 kW electric bottom heating, a 0.55 kW geared agitator drive with scraper agitator, an immersion thermometer for monitoring product temperature, a DN50 butterfly outlet valve, and height-adjustable support legs.

Optional equipment

• Curd knife for stirring and processing curd grain
• Interchangeable agitators for different processing applications
• Stainless steel or polymer scraper configurations
• Digital P control version with PT100 temperature probe and PID controller
• Frequency inverter for adjustable agitator speed
• Cycle timer for automatic control of the pasteurization holding stage
