Mozzarella production

Types of mozzarella production machines

A mozzarella production machine is an apparatus used to manufacture mozzarella cheese from milk. It involves combining milk and culture, heating the mixture, curd formation, curd cutting and cooking, curd mat, stretching, cooling, and storage. Several machines are used to make mozzarella because different methods are required at different stages. Some machines help automate the process, such as automated curd cutters that can be operated at the push of a button, and some assist with huge production lines, such as continuous flow pasteurizers and stretchers.

• Milk Pasteurization Equipment:

  Since raw milk can contain harmful bacteria, the first step in mozzarella production is to pasteurize milk using a continuous pasteurizer to kill any harmful bacteria. The milk is heated to a specific temperature for a specific period and cooled quickly. The milk is then pumped into a holding tank where cultures and rennet are added to form curds. The cultures added will help develop the flavor and texture of the cheese.

• Curd Cutting Machines:

  Cuts are made in the curd using curd-cutting machines. When the curd is cut, whey is released, and the curd is cooked to facilitate the whey release further. Cooking whey is done through whey cookers or incude cookers. The curds are cooked at a higher temperature to help the whey escape. When the cooking is done, the whey is drained from the curds through drainage conveyors or drainage tables depending on the method used to drain the whey. At this stage in the mozzarella cheese production process, the curds look like small rice-sized pieces.

• Stretching and Maturing Equipment:

  The curds can be matured using cheese vats or stretching vats, depending on what kind of cheese is being produced. Not all cheese requires maturation. The curds are then stretched. During the stretching process, the curd is heated and kneaded, which gives the cheese its well-known stretchy texture. Stretching equipment includes hot water baths, steam baths, and kneading machines.

• Packaging Equipment:

  Sous vide packaging machines can be used to package mozzarella cheese in vacuum-sealed bags, and automated baggers can help with high-volume production lines to package the cheese into bags.

Specification & Maintenance

The key machinery required for mozzarella cheese production are as follows.

• Milk pump

  The cheese production process begins with milk pumping. The milk pump transfers fresh milk to the pasteurizer. The flow rate of the milk pump is 1,000 – 3,000 liters per hour. The motor power varies depending on the size and type-it can range from 0.5 to 5 kw.

• Pasteurizer

  The main function of the pasteurizer is to eliminate harmful bacteria and extend the shelf life of milk. The working temperature of the pasteurizer ranges between 72 and 75 degrees. It also cools the milk to the desired temperature for mozzarella cheese production, which is around 35 to 40 degrees.

• Curd Making Vat

  This vat is where the milk is curdled. The Curd Making Vat comes with temperature control and stirring mechanisms. It can hold up to 3,000 liters of milk, and the dimensions are approximately 2-3 meters in diameter and 1 meter in height. The material is usually stainless steel, which is durable and hygienic.

  The Curd Making Vat needs regular maintenance and cleaning. The first step in the cleaning process is to remove any leftover curd or cheese from the vat. Then, hot water and a cleaning solution are added to the vat. The cleaning solution used should meet food safety standards. Next, stir and scrub the vat surfaces. After this, thoroughly rinse the vat with potable water to remove any residue of cleaning solutions. The Cleaning of Curd Making Vats should be done at least once a week for thorough cleaning. Routine cleaning should also be done daily to prevent residue buildup.

• Stirring mechanism

  The stirring mechanism mixes the rennet and the acid into the milk. It ensures a uniform distribution of ingredients. The speed of the stirring mechanism varies according to the required texture and consistency. It usually ranges from 10 to 30 rpm.

• Draining mechanism

  After curd formation, the draining mechanism separates whey from the curds. It can be in the form of a conveyor belt or a separate container. The draining mechanism may have filters and screens to prevent curds from passing through.

• Stretching vat

  The curd is heated in the stretching vat when making mozzarella cheese. The heating mechanism can be direct or through hot water jackets. The stretching vat can hold 5,000 to 10,000 liters of curd. After heating, salt is added to the curd for flavoring. The temperature for stretching is around 85 to 95 degrees, and the time for stretching is around 10 to 20 minutes. The material of the vat is usually stainless steel or coated carbon steel.

• Packaging machine

  When the mozzarella cheese is ready, a packaging machine is used to package the cheese. In the case of mozzarella sticks, the cheese is first cut into sticks or any shapes (using a forming machine) and then packaged. The packaging machine can be of two types (i) modified atmosphere packaging (MAP) and (ii) vacuum packaging machine. The packaging machine may also have a marking machine that stamps the date and barcode on the cheese product. The packaging machines have various technologies, and the speed ranges from 50 to 300 packages per hour.
