Batch Pasteurizer Double BP 400 (200×2)

The Batch Pasteurizer BP 400 is designed for controlled heat treatment of food products in batch production.

The pasteurizer consists of two 200-liter baths equipped with electric heating elements and a basket system for convenient loading and unloading of products. It can be used for processing products in glass jars and other suitable containers, as well as loose food products requiring controlled thermal treatment. It is suitable for a wide range of food-processing applications, including the production of preserved vegetables, fruits, sauces, ready-made foods, and other products where pasteurization is used to improve microbiological stability and extend shelf life.

The two-bath configuration provides flexibility in production and allows batches to be processed separately. Depending on the production requirements, the baths can also be equipped for separate heating.

Pasteurization system and temperature control

Water in the baths is heated by electric heating elements. Products are placed into the baskets and immersed in the heated water for the required pasteurization process.

The temperature is monitored by a thermometer probe and controlled automatically. Once the preset temperature is reached, the heating system automatically switches off, helping maintain controlled processing conditions. The required pasteurization temperature and holding time depend on the product, container size, formulation, and desired processing result and can therefore be selected according to the specific production process.

The maximum heating temperature of the equipment is 90°C, providing a suitable operating range for many batch pasteurization applications. The two-bath configuration also allows different batches to be processed separately and can be useful when handling different products or processing conditions during production.

Applications in the food industry

The BP 400 can be used for batch pasteurization of a wide range of food products, including:

• vegetables and vegetable products
• fruits and fruit products
• mushrooms
• sauces and prepared foods
• products packed in glass jars
• preserves and canned-style products
• ready-to-eat foods
• other products requiring controlled water-bath heat treatment

For packaged products, the baskets allow jars or other suitable containers to be loaded and immersed in the heated water bath for controlled thermal treatment. The equipment is particularly suitable for small and medium-scale food production, where products are processed in batches rather than through a continuous pasteurization system. The pasteurizer can be used as an individual processing machine or integrated into a larger food production line together with other FoodTechProcess equipment.

Processing of products in jars

The BP 400 is suitable for pasteurizing food products packed in glass jars and other suitable heat-resistant containers. The filled containers are placed into the baskets and immersed in the heated water. This principle is suitable for products such as preserved vegetables, mushrooms, sauces, fruit preparations, jams, ready-made foods, and other packaged products requiring controlled thermal treatment.

The water bath provides heat transfer around the containers, while the controlled temperature allows the pasteurization process to be carried out according to the requirements of the particular product and packaging format.

Main components of the batch pasteurizer:

• two 200-liter stainless-steel baths
• electric heating elements
• thermometer probe
• water level control
• product baskets
• electric crane for basket handling
• automatic temperature control system

The electric crane facilitates lifting and moving the baskets, making the loading and unloading of products more convenient and reducing manual handling.

Advantages

• Two separate 200-liter baths provide flexible batch production and allow different batches to be processed independently.
• Automatic temperature control maintains the selected water temperature and reduces the need for continuous manual monitoring.
• Suitable for jars and other containers makes the equipment suitable for preserved vegetables, fruits, sauces, ready-made foods, and other packaged products requiring pasteurization.
• Suitable for loose food products allows the equipment to be used not only for packaged products but also for suitable products requiring controlled water-bath heat treatment.
• Electric crane for basket handling simplifies loading and unloading and makes handling of filled baskets more convenient.
• Easy-to-clean stainless-steel construction is suitable for food-processing environments and facilitates routine cleaning and maintenance.
• Maximum heating temperature of 90°C provides a suitable temperature range for many food pasteurization processes while allowing the thermal treatment to be adapted to the requirements of the particular product.
• Separate bath heating is available as an option, allowing the two baths to be operated according to different production requirements.

Construction and operation

The pasteurizer is manufactured from AISI 304 stainless steel, providing a durable and hygienic construction suitable for food production. Products are loaded into the baskets, which are then placed into the pasteurization baths. The water is heated by electric heating elements and the temperature is monitored automatically. After the required thermal treatment has been completed, the baskets can be lifted from the bath using the electric crane. The simple batch principle makes the equipment suitable for food producers requiring controlled pasteurization without the complexity of a continuous processing system.

Integration with other food-processing equipment

The BP 400 can be used as part of a complete food-processing workflow. For example, vegetables, fruits, and mushrooms can first be washed, sorted, cut, or otherwise prepared before being filled into containers and pasteurized in the BP 400. The pasteurizer can also be combined with cooking kettles, mixers, filling and sealing equipment, and other FoodTechProcess machinery, depending on the required production process.

For sauces, vegetable preparations, fruit products, jams, and other processed foods, the pasteurization stage can follow cooking and mixing and can be integrated with subsequent packaging operations. This makes the BP 400 suitable both as an individual batch pasteurization machine and as a component of a more complete food-processing line.
