19 MODULAR WALK IN COOLER S & MODULAR WALK IN FREEZER S : This series of walk-in cooler cold rooms and walk-in freezer cold rooms are standard modular cold room. Different standard dimension of cold-room length,width,height is available.

20 Storage temperature of the walk in cooler & freezer can be optional -5 or -20 for the refrigerating storage or freezing storage of fresh vegetable & fruit or frozen food. The modular walk-in freezer & cooler cold room can easily assembled or disassembled by customers in their own location. The cold room panel of the walk in cooler and walk in freezer is made by high density polyurethane with an average density of 40kg/m3 for a good insulation.

21 Cam lock tongue and groove panel cold room design with gasket makes the walk-in cooler & walkin freezer perfect sealing. Strong, stable and high quality walk-in cooler & freezer condensing unit and fan coil unit for various ambient temperature. Digital thermostat of the cold-room gives precise temperature control and temperature display.

22 COLD STORAGES : Commercial Cold Storages of both customized walk-in cooler cold storage and walk-in freezer cold storage are available for the cold storage and frozen storage of different cooling and freezing purposes. The customized designs of modular units can be adapted to any storage space of length,width & height. The cold storage room warehouse is customized for the needs of flexible tailor-made construction dimension of length, width and height.

23 RIPENING CHAMBERS : Fruits are green and immature...events must now happen to cause it to ripen so that it is attractive and rewarding to carry it off... In the diagram above on the left is an unripe fruit. It is hard, green, sour, has no smell, is mealy (starch present), and so on. Sometimes we crave such a combination of characteristics... The way fruits ripen is that there is commonly a ripening signal...a burst of ethylene production. Ethylene is a simple hydrocarbon gas (H2C=CH2) that ripening fruits make and shed into the atmosphere. Sometimes a wound will cause rapid ethylene production...thus picking a fruit will sometimes signal it to ripen...as will an infection of bacteria or fungi on the fruit. This ethylene signal causes developmental changes that result in fruit ripening. New enzymes are made because of the ethylene signal. These include hydrolases to help break down chemicals inside the fruits, amylases to accelerate hydrolysis of starch into sugar, pectinases to catalyze degradation of pectin (the glue between cells), and so on. Ethylene apparently "turns on" the genes that are then transcribed and translated to make these enzymes. The enzymes then catalyze reactions to alter the characteristics of the fruit.

24 The action of the enzymes causes the ripening responses. Chlorophyll is broken down and sometimes new pigments are made so that the fruit skin changes color from green to red, yellow, or blue. Acids are broken down so that the fruit changes from sour to neutral. The degradation of starch by amylase produces sugar. This reduces the mealy (floury) quality and increases juiciness (by osmosis, a process we will study later). The breakdown of pectin, thanks to pectinase, between the fruit cells unglues them so they can slip past each other. That results in a softer fruit...at an extreme, pectin losses may make a fruit "pithy". Also enzymes break down large organic molecules into smaller ones that can be volatile (evaporate into the air) and we can detect as an aroma. Our ripening chamber maintains the precise conditions required by each specific application. Factors such as humidity, temperature, ventilation, and specific gas emission levels within each ripening chamber are tuned to optimum levels in each chamber design, based on requirements at each facility. Example: Typical conditions for ripening banana and mango.
