Blenders and Mixers

Eliminates the conventional vacuum receiver, its loading and discharge .Transfers all the material into the process without spills, waste. Keeps housekeeping to a minimum.

 Transfer can be completely automatic, eliminating the manual handling of the material.
Avoids product waste, loss and contamination. Material is drawn from floor level through clean hose or tubing. Operating personnel are not exposed to dusty or harmful material.

Systems are packaged with timing controls and automatic pulse filter cleaning. Controls and vacuum pump can be remotely located.

Blender loader hopper is easily removed from frame for washdown, leaving controls and power components in place.

Blender cover modifications are routine, or standard adapters are available for many models.

Complete range of pneumatic accessories include pick-up wands, feed bins and bag dump stations.

Power options include VAC-U-MAX vacuum pump packages from 3 hp up and the exclusive ,VAC-U-MAX venturi power unit.

Available standard in 304 stainless steel and 316 stainless steel. Food and pharmaceutical grade finishes available.



Loading a Loss in weight feeder that is operating in a continuous mode requires the right kind of equipment. The objective is to refill the feeder as quickly as possible. VAC-U-MAX offers the fastest way to reload a feeder in the material handling business. Many times the Feeder is purchased without consideration of how the feeder will get filled and refilled. 






VAC-U-MAX has designed a number of bulk bag loading frames for different applications and will aggressively respond to all bulk bag loading opportunities. Two frames are offered as standard MDL104130A and MDL1041308. In general, the frames from VAC-U-MAX are simple, sturdy frames of square tubular construction with four legs and permitting a great number of loading options, including the supports for these. A simple bungee cord bag neck damp offers a major advantage in being able to seal any bag neck from 13 inch diameter to 24 inch diameter without changing the bag neck spout. An inflatable cuff, which is common on competitive units, is offered as an option. The disadvantage of this device is that a single size cannot accommodate a wide range of bag necks . The versatile and simple single venturi power unit with venturi discharge provides a source of low pressure air for bag inflation. A filter for the air displaced from the bag Is standard





Ideally suited for handling powders, granules, tablets, capsules and other pharmaceutical items, vacuum pneumatic conveyors can also be designed to deliver closures and moderate-sized containers to filing lines.





VAC-U-MAX combines modern computerized technology with innovative mechanical and pneumatic design to produce ingredient handling systems that not only free operators of physical effort but also perform sophisticated pneumatic conveying operations with little human assistance.

Each system we design is custom engineered for the application parameters provided by the customer, to ensure that the system will perform to exact requirements.

The system conveys three different ingredients from drums to the weigh hopper and automatically batches them to precise weights, in various preprogrammed formulations. They are then automatically discharged into a surge hopper and adapter spout, which can be rotated to load any of three mixing tanks. A micro-processor-based control panel provides the flexibility to add, change or delete formulations as required.



Compact design receiver package with rates of 200-250 Kg. per hour.

Eliminate manual scooping of product and messy dumping or mishandling. Draw material directly from drums, boxes, storage containers, process vessels.
