Environmentally controlled vending machine for humidity sensitive products
First Claim
1. An environmentally controlled vending machine for selectively dispensing humidity sensitive products, comprising:
- a housing;
a holding mechanism within said housing for storing products in a manner for selective dispensement;
a selection mechanism operatively associated with said holding mechanism configured to facilitate the dispensing from said holding mechanism of a selected product;
a sensor for monitoring humidity and at least one environmental parameter within said housing;
a microprocessor in communication with said sensor for obtaining a differential value approximately equal to a difference between said monitored at least one environmental parameter and a target value defined for said at least one environmental parameter; and
means in communication with said microprocessor for adjusting said at least one environmental parameter to minimize said differential value.

Abstract
An environmentally controlled vending machine utilizing real-time monitoring of environmental parameters and feedback control for improved storage conditions for tobacco products such as cigars and other humidity sensitive products, is disclosed. A number of environmental parameters, such as temperature and humidity, are balanced using a closed loop feedback control process in response to measured system parameters. The vending machine includes a controller, one or more remote sensors which monitor the environmental conditions within the vending machine housing, a fan, a heater strip, a cooling unit, a humidifier, and a payment and selection system. The vending machine stores and maintains tobacco products, or other humidity sensitive products, at a recommended temperature and humidity, and includes means for continuously monitoring and controlling the environment to retain the freshness and value of the respective product. In order to best maintain the freshness and value of the tobacco products, for example, the vending machine preferably stores the products at approximately 70° F. and a relative humidity of approximately 70%.
