About This Product

■Product overview

- Generates hot water using the heat of raw milk. At the same time, raw milk is pre-cooled at a low temperature. ・First in the industry. Simultaneous extraction of cold and hot water using heat pump technology reduces costs and environmental impact Dairy farming requires large amounts of hot water for cleaning and disinfecting equipment and buildings, and the cost of fuel for boilers and other hot water generators is a significant burden. On the other hand, there are also costs for cooling water and electricity for bulk coolers to quickly cool down the raw milk that is produced. This product is the industry's first system that uses heat pump technology to solve the waste of separate heating and cooling systems. By introducing a heat pump heating and cooling cycle that recovers and reuses the heat from raw milk, we can significantly reduce the costs previously incurred and also contribute to reducing the environmental impact.

■Features of this system

・Generate hot water by recovering heat from raw milk using a heat pump - Low temperature pre-cooling of raw milk using system circulating water (approximately 5℃) ・Uses heat pump with CO2 natural refrigerant

■Advantages after introduction

・Obtain high-temperature water needed for equipment cleaning without a boiler ・Significantly reduces cooling water consumption ・Stable cooling is possible throughout the season. ・Suppress bacterial growth with low temperature pre-cooling ・Suppress the cooling energy of the condensing unit with low-pitched precooling ・Natural refrigerant that is more environmentally friendly than fluorocarbon gas ・Reducing maintenance costs due to laws and regulations

■Energy and water saving effects of this system

The milk heat pump system eliminates the need for a boiler, reducing fuel costs, and using a highly efficient heat pump, it also reduces electricity costs. Energy is saved in both the heating and cooling processes, and the annual cost is reduced to less than 1/3 under the following usage conditions.
