Progress and development in brick wall cooler storage system

Abstract

a b s t r a c tThis paper carried out a review study into the brick wall cooler storage system (zero energy storage) in terms of its originality, current status, research and implementation achievement, benefit and possible barriers. The continuous progress in technology innovation, heat and mass exchanger of the brick wall cooler storage system now varied from sand-zeolite mixture, volcanic plate made wall, natural ventilation for releasing excess inside relative humidity, optimization of watering operation to save water and successful integration of the solar-driven adsorption cooling system with brick wall cooler storage system enhanced the cooling performance over those the decade ago by increasing the shelf-life of the stored fruit and vegetables. This review work indicated that the brick wall cooler storage system has potential to be an alternative to conventional electric powered expensive cooling storage for fruit and vegetables in the rural areas of the developing world. Future success on the dissemination of brick wall cooler storage system towards farmer's community may imply on more study on newer type of low cost heat exchanger material; further study on its economic, environment and social impacts; low cost postharvest treatment and packaging for brick wall cooler storage system; extensive farmers awareness and other dissemination measures; and public awareness and other dissemination measures.

Evaluation of temperature and relative humidity on two types of zero energy cool chamber (ZECC) in South Sulawesi, Indonesia

“…Spoilage was maximum in unvented poly bags under ambient and zero energy cool chamber conditions. Storing banana fruit in unvented poly bags at low temperature could extend the shelf-life of the fruit up to 19.33 days [7]. From the above studies, it can be seen that all of their ZECC was constructed on the surface.…”

“…The design was based on the evaporative cooling of a porous body [1,7,9,10]. Two different of ZECC were constructed.…”

“…The physiological loss in weight and rotting percentage increased at room temperature but decreased with increasing water level up to 100 l per day. As a result, the shelf-life of Brinjal enhanced to 9 days with the addition of 100 l of water per day [7]. Narayana et al [8] investigated the quality of banana packed with low-density polyethene bag with or without ventilation under different storage conditions, namely, ambient temperature, zero energy cool chamber (brick-sand evaporative cooler) and 13.5 0 C low temperature.…”

Application of palladium‐modified zeolite for prolonging post‐harvest shelf life of banana

“…However, the traditional post‐harvest technologies for controlling the release of ethylene gas from fruits may not be desirable. This is because present technologies tend to have high transportation and operation costs, energy demands, and potentially produce toxic chemicals . Ethylene removal using zeolite as an adsorbent has received considerable attention in both industry and agriculture application .…”

“…This is because present technologies tend to have high transportation and operation costs, energy demands, and potentially produce toxic chemicals. 3,[10][11][12][13][14] Ethylene removal using zeolite as an adsorbent has received considerable attention in both industry and agriculture application. [15][16][17][18] Trinh et al 16 compared the efficiency of three different zeolites for adsorbing ethylene from an air steam and showed that silver (1.0%)/13X zeolite had high ethylene adsorption affinity.…”
