Design
The working parts are totally enclosed to provide a functional exterior that is smooth, streamlined, easily cleaned and virtually hose-proof. For the servicing and cleaning of interior parts there is a lift-off panel at the back.

Power
A vertical motor transmits power to the mixing mechanism and the arrangement is fully reliable, and simple for easy maintenance. At all speeds 6 hp is transmitted thus permitting the mixing of highly viscous materials such as toffee, etc. The standard mixer gives final speeds of 40/60/120 rpm but single, two and four speed models are available.

Pan
The pan can be of copper or stainless steel with a mild steel jacket or have a stainless steel inner shell with all-welded mild steel jacket. When a copper pan is used, we can fit this with a stainless steel mouth for added strength. Tilting is by hand operated safety worm gear which cannot over run. A non-tilting pan with bottom outlet is also available. A rigid lid, which automatically locks in the open and closed positions, obviates spillage at any speed. For inspection of the mix or addition to it, a hinged panel is incorporated and a connection is provided for steam extraction.

Steam Jacket
The jacket, which has an automatic air release valve, can be designed for steam pressures up to 150 psi. Both jacket and pan are tested in our works to one and a half the working pressure and a certificate is issued for insurance purposes.

Agitator
On standard machines this consists of a highly polished gun metal
outer bow* to which are attached hinged scrapers that contact the entire working surface of the pan. Inside these are simple acting or contra-rotating stirrers.

Mixing head
This is very robust and made to withstand fast mixing speeds. It houses its own oil bath, but oil cannot leak to contaminate the mix. The head is raised and lowered by a 3/4 hp independent motor with magnetic brake which operates at both extremes. For safety, the drive to the agitator is cut out by limit switches when the head is moved from the working position. In emergencies such as a power cut, the head can be moved manually.

Lubrication
All main drive components are lubricated by a circulating pressure system requiring minimum attention. A gauge for assessments of function is conveniently located. Subsidiary points, which only require lubrication at intervals, are served by centrally grouped grease nipples.

Electrics
All connections are complete for immediate attachment to the mains. The control gear is housed in a movable cabinet and consists of isolator switch and the push buttons for controlling the three speeds of the stirrers and raising and lowering of the mixing head.

Extras Available
This machine can also be supplied as a vacuum unit to customer's requirements.

Universal Batch Cooker / Mixer

The Universal Batch Cooker / Mixer, Model UBC1, is steam jacketed for working pressures of 7-8 atmospheres (100-120 psi) and is pressure tested to 12 atmospheres (180 psi).

The process of cooking and vacuuming is done separately. Once the product has been cooked in the upper copper jacketed mixing pan it is then discharged by means of a handwheel-operated centre valve to the lower copper vacuum pan. At the same time as the vacuum operation is taking place, the upper cooker / mixer section can be prepared for the next batch. Discharge from the vacuum pan is by swing-out handle and then by tipping.

A light is provided in the vacuum chamber to facilitate observation of the batch through inspection window.

The mixing arms are made of stainless steel and drive is by a two-speed motor.

The thermometer bulb is built in and projects into the mixture mass the whole time. this ensures precise temperature readings.

The machine is supplied with thermometer, vacuum gauge, pressure gauge, safety valve and vacuum pump.
