Providing the product you need

B&P Littleford manufactures a wide variety of mixing and separating equipment ideal for food and beverage processing. This includes mixers, both batch and continuous as well as the TriVolution Compounder. B&P Littleford’s POD centrifuges are extensively used for liquid-liquid extraction and separation, while the pusher centrifuges efficiently and proficiently separate liquid-solid slurries.

BATCH MIXERS

Horizontal Plow Mixer

B&P Littleford Horizontal Plow Mixer creates fluid mixing action. The mixing tools project and hurl material away from the wall into free space in a crisscross direction, and inversely back again. The plow separates and lifts the product in a three-dimensional motion, while the number and arrangement of the tools insure agitation back and forth along the length of the vessel.

The size, number, geometric shape, arrangement, and peripheral speed of the mixing tools are designed to achieve this mixing action for each specific application. When required, the mix action is assisted by high shear chopper devices: independent high-speed motors with customized blades for adding shear to the product mix.

The Horizontal Plow Mixer also features:

Large doors allow full interior access
CIP/SIP hardware options available
"Easy Clean" design available for batch or continuous material mixing
Split seal assembly
No special cleaning or maintenance tools required
Bearings and drive components not disturbed during cleaning

CONTINUOUS MIXERS

Continuous Kneader

B&P Littleford Carbon Paste Continuous Kneaders (CK-CP Kneaders) are ideal for food and beverage processing.

Delivers maximum throughput
Provides consistent mixing
Efficient mixing mechanism
Easy access for maintenance
East to maintenance costs
Segmented system design means minimal tear-down required for maintenance or part replacement
Peak shear rate lower than other compounders
Operates at comparatively lower internal pressure
Uniformity of temperature, pressure and narrow residence time distribution
Greater surface area, more free volume and higher specific torque capability
Total shear strain is controllable by adding or removing pins and flights
Ability to measure melt temperature or inject liquids at any point along the process
Efficient self-wiping mixing mechanism

B&P Littleford’s Continuous Kneaders are available in a wide range of screw sizes and include an array of features:

TriVolution®

With its unique and innovative design, B&P Littleford’s TriVolution® Compounder offers excellent dispersive and distributive mixing without damaging critical ingredients.

B&P Littleford’s TriVolution® Compounder reciprocates the process screw three times for every one revolution. Flights interact with pins in the barrel much in the same way a continuous kneader does. Its controlled shear with enhanced material exposure also works well for devolatilization and reactive processing.

The TriVolution Compounder features:

Energy efficient
Cost effective
Uniquely design allows for faster mixing

SEPARATION EQUIPMENT

Podbielniak® Contactor (POD®)

B&P’s Podbielniak® Contactor (POD®) is a horizontal axis liquid-liquid centrifugal extractor that processes liquids for accelerated solvent extraction. The two main functions of this machine are liquid-liquid separation and the liquid-liquid extraction process through counter-current flow.

Use the POD for:

Liquid smoke
Citric Acid
Citral extraction from Limonine
Hops extraction
Cooking oil
Oleic Oils
Lauric Oils

B&P’s Podbielniak® Contactor (POD®):

Reliable: POD® has been in service for more than 60 years
Runs smoothly: Uses a dual bearing lubrication system - one for normal operation, one for flush cleaning
Durable: Lower operating rpm means rotating parts last longer
Easy to clean: Rotor elements use Asco tubes and Ferralium alloy liners
Sturdily construction: Made of 316 stainless steel. Non-contact parts and attachments in 304 stainless steel and chrome

Innovative Dextrins Manufacturing

B&P Littleford’s technology brings efficiency and economy to manufacturing Dextrin, a carbohydrate with the same general formula as starch.

Manufacturing commercial Dextrin is usually a costly, time-consuming process that yields an inconsistent end product.

B&P Littleford has developed a superior system for manufacturing Dextrin in a single vessel.

Here’s how it works: Starch is charged into the processor unit. Starch is dried with hot air to ensure proper moisture levels. When moisture is removed and starch reaches a required temperature, HCl gas is injected onto the starch. After a predetermined reaction time and temperature, the product is ready for additional processing, cooling and discharging.

B&P Littleford’s Dextrin process provides:

Better conversion efficiencies
Controlled temperatures through heat transfer
Improved production rates
Efficient single unit processing during chemical reaction process
Elimination of black specks in dextrin
Capability of agglomerating the fine dextrin powder in the same unit
Capability of blending in a flow agent
Compliance to FDA, 3A, USDA standards

Delivering the service you deserve

B&P Littleford designs, develops and delivers a wide range of mixing, drying, compounding, reacting, extracting and centrifugal separation equipment for many different manufacturing applications.
