:: Washing Of Citrus ::

Citrus is washed in dump tanks or high pressure spray units with a disinfectant in order to inactivate the spores of the post harvest fungal diseases and to reduce bacterial contamination in wash waters from a food safety perspective. In many instances the water used is of poor quality in that it contains suspended solids, organics and is microbiologically contaminated. These factors complicate the requirements of meeting the customer's need of high quality fresh produce with no spoilage.

Note: the use of a disinfectant in this application is only to reduce the inocculum load in the water. The fungicide treatment gives protection against spoilage over the period of transportation and distribution.

Secondly, add 1 litre of an alkaline degreaser per 100 litres of water and use this solution to clean the tanks. Third step would be to rinse off the detergent. Finally, spray with a solution of activated Harvest Wash WT and allow to air dry.( This " activated " solution contains 1 litre Harvest Wash WT with 100 ml Activator which is then diluted into 100 litres of water)}.
6. Note: to treat water for fungal and bacterial control we require 1 litre Harvest Wash WT per 1000 litres of water. To use as a sanitiser we need 1 litre Harvest Wash WT per 100 litres of water.

We always give only the dosages of Harvest Wash WT since it is always used in conjunction with the Activator.
