Produce processing dosing system
A system ( 10 ) for treating produce includes an application system ( 12 ) for applying a treatment liquid to the produce. A piston pump ( 20 ) is connected in liquid flow receiving communication with a source of treatment liquid ( 16 ), and also is connected in liquid flow expelling communication with an application line ( 18 ) leading to the application system. A control system ( 22 ) controls the operation of the piston pump to pump a selected dosage of the treatment liquid from the source of treatment liquid ( 16 ) to the application system ( 12 ).
1. A dosing system for applying at least one treatment liquid to food products, comprising:
a piston pump connected in liquid flow communication with a source of treatment liquid, the piston pump also connected in liquid flow communication with an application system for applying the treatment liquid to the produce;
a control system for controlling the operation of the piston pump to pump a selected amount of the treatment liquid from the source of treatment liquid to the application system;
further comprising an application vessel to receive the treatment liquid from the piston pump; and
further comprising a recirculation pump in communication with an application line to circulate treatment liquid from one location of the application vessel to another location of the application vessel.
2. The dosing system according to claim 1 , further comprising a flow control valve between the source of treatment liquid and the piston pump.
3. The dosing system according to claim 1 , further comprising a flow control valve between the piston pump and the application system.
4. The dosing system according to claim 1 , further comprising a water source for supplying water to the application vessel for dilution of the treatment liquid received from the piston pump.
5. The dosing system according to claim 1 , further comprising an application pump for pumping the treatment fluid from the application vessel to the food product being treated.
6. The dosing system according to claim 1 , further comprising a mixing apparatus in communication with the application line for mixing the treatment liquid flowing through the application line.
7. The dosing system according to claim 1 , wherein the source of treatment liquid comprises a storage vessel in flow communication with the piston pump.
8. The dosing system according to claim 1 , further comprising:
a plurality of piston pumps, each connected in liquid flow communication with a source of treatment liquid, the piston pumps also each connected in liquid flow communication with the application system; and
a control system for controlling the operation of the piston pumps to pump a selected amount of the treatment liquid from the source of treatment liquid to the application system.
9. The dosing system according to claim 1 , further comprising a linear actuator connected to the piston to reciprocate the piston within the cylinder.
10. The dosing system according to claim 9 , further comprising a motor for powering the linear actuator for reciprocal movement.
11. The dosing system according to claim 1 , wherein the treatment liquid from the piston pump is in communication with the application line.
