Abstract

A system providing for on-site reclamation and re-use of reclaimed antimicrobial solution includes a dispenser, at least one receptacle, piping, and at least one pump. The dispenser sprays antimicrobial solution toward moving raw food products. Unspent antimicrobial solution that did not contact the moving raw food products and rebound antimicrobial solution that did contact the raw food products combine to form a reclaimed antimicrobial solution. The reclaimed antimicrobial solution is collected in the receptacle and is pumped through the piping to a location for reuse.

First claim

What is claimed is:

1. A method for on-site reclamation and reapplication of reclaimed antimicrobial solution in a raw food product processing system, the method comprising:
(a) spraying an antimicrobial solution from nozzles arranged at a first side and a second side opposite of the first side of a disinfecting stage toward raw food products transported through the disinfecting stage;
(b) collecting unspent antimicrobial solution that did not contact the raw food products and rebound antimicrobial solution that did contact the raw food products to form a reclaimed antimicrobial solution in a first receptacle arranged on the first side and a second receptacle arranged on the second side;
(c) pumping the reclaimed antimicrobial solution from the first receptacle and the second receptacle through piping;
(d) transporting the reclaimed antimicrobial solution to a reuse location in the raw food product processing system; and
(e) spraying the raw food products with the reclaimed antimicrobial solution at the reuse location in the raw food product processing system.

2. The method of claim 1 , wherein the step of spraying the antimicrobial solution occurs continuously.

3. The method of claim 1 , wherein the steps of spraying the antimicrobial solution and spraying the reclaimed antimicrobial solution comprise spraying acidified sodium chlorite.

4. The method of claim 1 , further comprising reconditioning the reclaimed antimicrobial solution prior to the step of transporting the reclaimed antimicrobial solution to the reuse location.

5. The method of claim 4 , wherein the step of reconditioning the reclaimed antimicrobial solution comprises filtering the reclaimed antimicrobial solution.

6. The method of claim 1 , wherein the raw food products are transported along a conveyor through the disinfecting stage.

7. The method of claim 6 , wherein the disinfecting stage comprises a first wall at the first side and a second wall at the second side, the first and second walls being aligned parallel to a direction of movement of the conveyor.

8. The method of claim 1 , wherein the nozzles arranged at the first side form a first set of nozzles and the nozzles arranged at the second side form a second set of nozzles, wherein the disinfecting stage comprises a first wall at the first side, the first set of nozzles being mounted on the first wall, and a second wall at the second side, the second set of nozzles being mounted on the second wall, the first and second walls being aligned parallel to a direction of movement of a conveyor.

9. The method of claim 1 , wherein the first receptacle is positioned in an area below the first set of nozzles and the second receptacle is positioned in an area below the second set of nozzles.
