冷藏柜化霜水蒸发不溢出设计方案

化霜水蒸发,无需人工倒水是当前饮料冷藏柜发展的一个技术方向。接水盒是化霜水蒸发不可缺少的重要零件之一,如果接水盒的设计容积不够,使蒸发不彻底,将导致化霜水溢出流到地面。本文通过对接水盒的设计及试验,得到化霜水蒸发不溢出的设计方案。将产品投入市场使用发展,化霜水蒸发的试验方法需要完善,提出应增加排水量和蒸发量关系的测试。

Detection of Accidental Fish Defrosting Using Non-Destructive Ultrasonic Technique

A non invasive ultrasonic method is used to detect whether or not the frozen fish has suffered a partial or total accidental thawing. The time of flight and the peak to peak amplitude of the ultrasonic signals backscattered by fish are recorded during thawing. The comparison of the evolution curves and images corresponding to first and second thawing shows indicators of accidental thawing. The monitoring of thawing process showed that its assessment can be reduced to the measurement of the water content lost by fish. The attempt to replace the original water lost by fish in first thawing is analyzed. The influence of the transducer frequency on fish thawing evaluation is tested.
