Abstract
Abstract A moisture analysis system is provided to analyze and determine the moisture content of uniformly baked goods according to predetermined standards. The dielectric properties of the goods are tested by using a fringe field electrode and a comparator. The temperature of the goods is measured, and a compensation signal provided to the comparator so that a direct moisture determination may be made and recorded.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
150 words
A moisture analysis system for uniformly baked goods comprising: a fringe field electrode positioned for holding and for measuring the dielectric properties of said goods; comparator means including a comparator amplifier having one input coupled to said electrode to indicate the changes in capacitance of said goods as compared to a standard, and said comparator amplifier having gain compensation and capacitance tuning inputs for adjusting said comparator means for different types of baked goods; means for measuring the temperature of said goods and providing a compensation signal to said comparator amplifier, whereby said comparator means directly indicates the moisture content of said goods; means for detecting the presence of a sample of said goods to be tested; command indicators coupled to said detecting means by a sequence circuit to indicate what portion of the test sequence is being performed; and means for ejecting said sample coupled to said sequence circuit.
