How to Transfer Hot Sauce with Stable Flow?
Bonve Sanitary Rotary Lobe Pump – The Ultimate Solution for Processing High-Viscosity Peanut ButterHot sauce production often involves heating, blending, cooking and filling. During these steps, the product viscosity can change as temperature changes. Chili, tomato or vegetable particles may also affect the flow resistance and the required pump configuration.
An unsuitable pump may create excessive shear, entrain air or deliver an unstable flow to the filling machine. High temperature can also place additional demands on the mechanical seal, elastomer and product-contact components.
A sanitary rotary lobe pump provides positive displacement transfer with adjustable speed. This allows the operator to match the pump output to the sauce condition, tank level, pipeline resistance and filling-line demand.
Main Challenges When Pumping Hot Sauce
Sauce viscosity may change significantly during heating, cooling and holding.
Chili, tomato, garlic, onion or vegetable particles may require a suitable rotor and clearance configuration.
Excessive pump speed can increase aeration, foaming and unnecessary product stress.
High-temperature operation requires application-specific mechanical seal and elastomer selection.
Thick sauces and pastes may require sufficient suction conditions and properly sized inlet piping.
Unstable discharge flow can affect filling accuracy and create pressure fluctuations in the transfer line.
Rotary Lobe Pump Solution for Hot Sauce Transfer
Controlled Positive Displacement Transfer
The rotary lobe pump transfers product by moving a defined volume with each rotor revolution. With a variable-frequency drive, the pump speed can be adjusted for different sauce viscosities, temperatures, tank levels and filling rates.
Low-Shear Handling for Viscous Sauces
The non-contacting rotor design maintains clearance between the rotors and pump casing. When operated at a suitable speed, the pump provides gentle transfer and helps reduce unnecessary shear and aeration in hot sauce, ketchup, tomato paste and other viscous food products.
Application-Specific High-Temperature Configuration
For hot sauce applications, mechanical seal and elastomer materials should be selected according to the actual operating temperature, sauce composition, acidity, solids content and cleaning conditions. BONVE can review these conditions before finalizing the pump configuration.
Hygienic Product-Contact Path
The pump can be configured with stainless steel product-contact components, sanitary connections and suitable seal arrangements for food processing. CIP-compatible product-contact paths and optional SIP arrangements can be reviewed according to the process requirements.
Flexible Connection and Installation Options
Horizontal-port and vertical-port pump configurations are available to match different installation layouts. The pump can be supplied as a bare shaft pump or as a complete pump set with coupling, guard, geared motor and baseplate.
Typical Hot Sauce Applications
Hot sauce transfer from cooking kettle to storage tank
Chili sauce transfer to filling and packaging lines
Tomato sauce and ketchup transfer
Tomato paste and tomato puree transfer
Pepper sauce and condiment transfer
Sauces containing controlled-size vegetable or chili particles
Recirculation of viscous sauces during production
Transfer between mixing tanks, buffer tanks, IBCs and filling machines
Bonve has an advantage over lobe pump that no other company can match.
1.Rotor:The error of the rotors processed by CNC is extremely small. The unique rotor perfectly seals the inlet and outlet of the pump. The vacuum degree of the pump is up to -0.095MPA. The rotor material and type can be selected according to the characteristics of the pumped product.
2.Shaft: The transmission shaft is processed by CNC machining center, which has characteristics of high precision, high bending strength and strong wear resistance.
3.Pump cavity: The pump cavity is sealed by a pump cover that can be opened quickly, enabling quick maintenance of the pump. The pump body is processed by CNC machining.
4.Gears:High-precision, High-Standard synchronous gears have good meshing, smooth transmission, low noise, and excellent bearing capacity.
5.Mechanical seal:The seal material and type are selected according to the characteristices of the pumped product, to ensure zero leakage, no pollution, and more environmental production.
6.Bearings: Six bearings arranged in a separate arrangement increase the concentricity of the pump operation, enhance the bearing capacity of the shaft and make the pump running more stable, thereby increasing the service life of the shaft and the mechanical seal.
7.Gear box: The gear box is processed by CNC, with high precision, high concentricity and strong versatility.
8.Spindle:We use splines the bearings and spindle, makes the pump less likely to slip. The high-precision spline makes the pump run more smoothly, and the service life is much higher than that of its peers.
More applications
In addition to sauce transfer applications,Bonve stainless steel lobe pumps are widely used in the food, dairy, confectionery, beverage, and wine industries. Typical transfer media include: condensed milk, cheese, mayonnaise, yogurt, honey, syrup, sucrose, ketchup, tomato paste, butter, concentrated juice, jam, ice cream, 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.
