Abstract

A wheeled frame, supporting a series of chemical tanks connected to the manifold, which includes a high pressure pump for a high pressure, low volume, or low pressure, high volume, cleaning and sanitizing capability. It has a metered and controlled selected chemical injection produced by a high pressure proportioning pump downstream of the high pressure water pump which pumps chemicals from the chemical tanks into the pressurized fluid stream. An additional capability is a metered and controlled oil injection into a high pressure air stream, which also has a drying capacity when oil is not metered into the system. The unit requires connections for electrical, power, and air which are locally available in the areas to be cleaned. Cleaning and sanitizing may be readily achieved by use of a detergent foam, then a high or low pressure chemical wash and followed by a sterilizing solution, and then by a clear-water low pressure rinse, all of which is followed by an oiling of clean equipment. Quick disconnect service terminals provide fast and easy set-up and take-down of the unit.

Claims

1. A portable cleaning and sanitizing system comprising a wheeled frame having connections for water, electricity and air services;

a plurality of liquid holding, pressurizable tanks mounted on said frame, and each said tank arranged with a liquid outlet;

means for selectively forcing liquid through said outlets;

flow control and measuring means for each outlet;

first manifold means;

each said flow control and measuring means communicating with said manifold means;

water inlet means communicating with said first manifold means;

high pressure pump means connected to the outlet of said first manifold means for pressurizing fluid from said tanks;

second manifold means having inlet means and outlet means;

means connecting said high pressure pump means and said second manifold;

high pressure water pump means including by-pass means connected to said water connection and connected with said second manifold for selectively injecting high and low pressure into said second manifold;

means connecting said air service to said second manifold; and

nozzle means connected with said outlet of said second manifold for issuing various mixtures of liquids from said tanks, water and air.

2. A portable cleaning and sanitizing system according to claim 1 wherein air under pressure from said air service pressurizes said liquid holding tanks forcing said liquid from said tanks.

3. A portable cleaning and sanitizing system according to claim 1 wherein said liquid holding tanks are removable.

4. A portable cleaning and sanitizing system according to claim 1 wherein said high pressure water pump means is mounted on said wheeled frame.

5. A portable cleaning and sanitizing system according to claim 1 being further characterized by an oil containing tank, a line from said oil containing tank, and a nozzle on said line for issuing oil therefrom.

6. A portable cleaning and sanitizing system according to claim 1 wherein said water inlet means for said first manifold means by-passes said high pressure pump means.

7. A portable cleaning and sanitizing system according to claim 1 wherein said outlets on said tanks are independent of each other.

8. A portable cleaning and sanitizing system according to claim 1 wherein said various mixtures issuing from said nozzle means is at predetermined pressures.

9. A portable cleaning and sanitizing system according to claim 1 wherein said nozzle means includes a length of flexible hose for movement of said nozzle away from said wheeled frame.

10. A portable cleaning and sanitizing system according to claim 1 wherein said means connecting said high pressure pump means and said second manifold includes a check valve whereby fluid from said high pressure pump means exhausting into said second manifold exceeds the pressure issued by said high pressure water pump means.
