APPARATUS, METHOD, AND SYSTEM FOR APPLYING SUBSTANCES TO PRE-HARVESTED OR HARVESTED FORAGE, GRAIN, AND CROPS

摘要

An apparatus, method and system for applying a biologically active or chemical substance to a relatively large volume of harvested or pre-harvested crop includes relatively small container (20) of a mixture biologically active or chemical substance and water in fluid communication with fluid conduit (14). A pump (40) moves mixture from the bottle through the conduit. A source (40) of pressurized air is in fluid communication with the conduit to aerate the mixture. The aerated mixture is expelled through a nozzle (12) at distal end of the conduit. In one aspect, the controller (80) can monitor speed of the pump by monitoring operating voltage of the pump. Speed of the pump can be adjusted to adjust application rate. In one aspect, a process combines a flow of air through an orifice with the metering of a low volume of additive, such as an aid to preservation, to a crop as it is being cut or harvested to provide for even distribution of the additive to the crop.
