Direct Charge Blender Loading

The principle of vacuum transfer has been proven to be a “better way” to move many types of material and a giant step over manual handling. The technology exists for moving virtually any material that can be pulled through a hose or tube.

A unique adaptation of vacuum transfer is “direct charge blender loading,” when a vacuum tight process vessel becomes the primary vacuum receiver for material being charged into it.

VAC-U-MAX has pioneered this technique and now offers new, exclusive packaged conveying systems designed specifically for the direct charge loading of blenders, mixers, reactors or any vessel capable of withstanding a vacuum.

With your blender or mixer as the primary receiver, VAC-U-MAX provides the rest of the system: power source, filters, controls, adapters and most important of all, the know-how.

Model 109020 Cover Adapter with Built-in Multi-Filter

Eliminates carryover of product from blender, insuring batch integrity. For use with blenders having a minimum 10 cu. ft. capacity. Includes 19″ diameter cover, clamps and three, 6″ diameter X 16″ long filter bags in various material types.

Standard feature includes quick disassembly for easy cleanout. Camlock-type fittings and dust caps are optional. Material outlet available in 2″ to 3″ diameter range. Cover adapter must be removed before blending and replaced with standard cover.

Multi-filter cover adapter also available with vacuum outlet only. Can be used with standard VAC-U-MAX material inlet on opposite side. Except for certain materials, both eliminate need for separate blender loader system.

Also available are standard cover adapters without built-in filters. Select from four configurations of one or two tubes per cover. Tube diameters range from 1.5″ to 4″ and come with plain tube ends.

Blender & Mixer Direct Charge Accessories

  • Cover Adapters
  • Dummy Hose Station

Direct Charge Blender Loading Features

  • 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. This eliminates 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. This leaves 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.
  • Tow power options available. They include VAC-U-MAX vacuum pump packages from 3 hp up. The other is the exclusive VAC-U-MAX venturi power unit.
