Stainless Steel Food Grade Rotary Lobe Pump for Chocolate Cream
Chocolate is prone to solidification at low temperatures, posing strict requirements for the anti-solidification, startup performance and efficiency of transfer equipment. Bonve jacketed lobe pump is optimized for this specific need, integrating an exclusive jacket design outside the pump chamber. It adopts steam or hot water (flexibly selectable based on on-site working conditions) as the heating medium to achieve circulating heating and constant temperature insulation, ensuring chocolate maintains a smooth liquid state at all times. This effectively solves the problem of low-temperature solidification and guarantees stable equipment startup and continuous efficient transfer.
With its gentle conveying process and hygienic design, the pump does not damage the original texture and flavor of chocolate during transfer, while meeting the rigorous hygiene standards of the food industry. The product is widely suitable for the entire chocolate production process—whether it is chocolate mass transfer, filling operations or molding processes, it can provide stable and reliable transfer support, making it an ideal equipment choice for chocolate manufacturing.
More applications
In addition to chocolate transfer applications,Bonve stainless steel lobe pumps are widely used in the food, dairy, confectionery, beverage, and wine industries. Typical transfer media include: chocolate, condensed milk, cheese, mayonnaise, yogurt, honey, syrup, sucrose, ketchup, tomato paste, butter, concentrated juice, jam, ice cream, milk, yeast slurry, meat paste, jelly, condiments, soy protein, various beverages, and wine.

Working Principle
Bonve lobe pumps basically consist of two lobe rotors, which rotate synchronously driven by a pair of synchronous gears in the gearbox. The rotors are driven by the main shaft and sub-shaft to rotate in a synchronous reverse direction, which changes the pump capacity, builds up high vacuum and discharge pressure, thus an efficient pumping is formed. Gap is kept between the rotors and between the pump casing, no friction, long life, no damage, no physical and chemical reaction to the pumped products.
