Crop Chiller


Currently in the Agricultural Sector many industrial farms use pesticides upon the crops produced to then prevent investment loss and to cause greater farm product yield. Through evaluating the health hazard the associated with the use of pesticides an alternative method of controlling the weed growth and the unwanted insect problem then adversely effecting the crop yield is then being presented.


By using Nitrogen ( N2 )  vacuum effect cooling with water , or Carbon

Dioxide ( CO2 / dry ice ) as the cold  "sink" cooled by the refrigeration system ,then  via cooling  exchanger  causing air emitted as a cold vapor distributed by fuel less automated system to then flash chill the crops without harming the produce will then cause several re-activities. First the insects will more than likely prepare " for winter" leaving the plants alone or then voluntarily moving to a different location. An N2 harvesting  or CO2 harvesting mechanism will then also be powered by the fuel less generator system  such as  http://www.designdeskinc.com/hydraulic-draft-cycle.html


The temperature system for the freeze cycle  is at a temperature upon final discharge , ( post

thermal cooling  exchanger ),  as not to cause any possible injury due to accidental exposure to the skin.


The fuel less generator will also power the mechanism.


The chiller may then also be attached to the center pivot irrigation systems to then disperse cold air as a vapor to then cause unwanted weed growth and insect control. Bees don't usually pollinate at night  so they should not be harmed. Timing of the system also regulated referencing the sunrise and sunset.


Due to the variance of the types of crops different apertures then with slightly different design systems for the different type of produce being grown.  The base of the plants then may also be insulated so that the cooling "forced frost" will then not harm the established plants but will then prevent young weeds from then growing as their a bit more susceptible to the cold when seedlings.


A thin mil ( millimeter ) plastic tube then stretched across  a  large span of field then made so that an arch occurs when inflated by pressurized cold air  ( for spans of 500' to 1000' ). The large span tubes then connected to cold air blower units upon the terminal ends.  Arch height up to 60'.


Additionally  an cold air discharge inflation  "tube" will then vent the cold air unto the corp below and cause a "forced frost" to then control the pestilence allow for the farmer not to have the requirement of having to use insecticide. The chiller and powered blower to inflate the arch will also be by fuel less mechanism. 


The plastic tubes may also then be anchored to a pivot mechanism then to allow the a rigid support member to lower / or raise the terminal ends of the tube ( opposite side of the tube from the hing point upon the anchor ) . This allows for harvesting and farm implements to transverse across the field unencumbered .  The rigid support members are motorized allowing for then to be raised and lowered at the hinge pivot.


Critical for the proceeding design system is the air intake height so that the system drafts the air in at specified height... The "wick draft" then only allowing freezing temperatures at stipulated height to not damage the produce. The intake flow system will be filtered ( no insect intake ) and will be as a long bar with louvered dampener shutters to adjust the flow volume.


The length then determined by Arch span length.the "stipulated height" then determined by the type of produce.  Also as a feature with in the air intake "bars" a hot air discharge may be used to the cause a stir... assisting in correct thermal management above the " Stipulated Height / ie. freeze elevation altitude ". The off set hot air rise discharge ports then in different furrows with hot air plume vents at the stalk base above the " stipulated height " .


The "air bars" may also be made to discharge cold air between the furrows to then also have the chillers at the terminal ends. The pieces can then also be made to connect end to end for long spans. 


When spraying with a pesticide... a cost is involved... also then including the diesel for the tractor and the pesticide itself.. With our system it will be less expensive overall and will not require repeated poisoning of the farm crop... Plants are like sponges  wicking water... when sprayed with a poison then entering the soil and water cycle the pesticide is traceable in the food....


Mulch decomposition  heating system may also be used to then, via tube thermally conductive , send warm water around the stalk of the produce to assist in the safety of the plant.


A small wheeled unit then with visual capacity then also an identifier data base may then be used for certain type of crops then also to observe report and and target locate weeds and or problem  areas upon the field also able to then target chill weeds 24/7 via cold air discharge venting from the terminal end of a hinged articulating robotic servo "arm".
