(a) The pre-cooling effect of the cost vacuum pre-cooling method is the best, but the cost is higher. To achieve the same pre-cooling rate and low cost, both crushed ice pre-cooling and ice-water pre-cooling can be tried. (II) Characteristics of the Park Products The above-mentioned crushed ice pre-cooling and ice-water pre-cooling have high pre-cooling rates and low costs. However, the treated products must be immersed in water. If the product is not water resistant, air precooling should be considered. (c) The longer the demand for garden products to be transported or stored, the more precooling is required. Conversely, there is no need for pre-cooling when it is only sold to nearby markets. There are considerable benefits from the rapid cooling of vegetables after harvesting, especially in gardens where the respiration rate is high or tissue fibers are susceptible to microbial infections. Low temperature is one of the most important measures to maintain quality and prolong transport life. However, precooling is only the first step in good temperature management. Pre-cooled products must be combined with a cryogenic transportation system or a cold storage system in order to fully realize the effects of precooling.
