Abstract

Fresh vegetable box is a box including a gas control device, uses of the principle of controlled atmosphere to keep fresh vegetable effect. In the preservation process, the fresh vegetable box can not be so easy to obtain uniform velocity field because the parameters of the box have different effects, and it will affect final preservation effect of fresh vegetable box. In this paper, a fresh vegetable box based on multiporosity material was recommended. 5 different cases were candidated and analyzed for investigating the effect of the property of the multiporosity material. The analysis results show that the property has an important effect to final velocity uniformity. The developed product and method can be used to develop a high performance fresh vegetable box.

1.Introduction

Fresh vegetable box can be defined as an original box including a gas control device, disperses the gas to the box uniformly, so as to achieve the purpose of freshing vegetables [1-3].

Optimization methods of the fresh vegetables and its examination of the characteristics have been very mature, but the problem about the optimization of the fresh vegetable box has not been launched widely.In the preservation process, the fresh vegetable box can not be so easy to obtain uniform velocity field because the parameters of the box have different effects, and it will affect final preservation effect of fresh vegetable box [1-3].

In this paper, the effect of a property of multiporosity material to velocity uniformity of a fresh vegetable box was investigated. At first, a fresh vegetable box based on multiporosity material was recommended. In the following step, 5 different cases were analyzed and discussed.
