Moisture woes during onion storage
Onions are grown in two seasons of the year and stored for the remaining. During storage, moisture causes microbial activities, root growth and decay. Sprouting occurs because of higher temperatures. In order to make onions available all through the year, warehouse and cold store owners have to ensure appropriate conditions for storage, which are
- Dry bulb temperature of 2-3ºC
- Relative Humidity of 65-70%
The existing methods for storing onions are not very convenient or economical. The best method for storing onions is Dehumidified Cold Stores.
Dehumidified Cold Storage . . .ensures that onions pack a punch even after 6 months of storage
Cold store owners stand to profit a lot by converting cold stores into dehumidified cold stores. Ensuring relative humidity of 65-70% RH through a Bry-Air Desiccant Dehumidifier ensures that onions remain fresh for months. Correct application enables recovery of costs within the first season itself.
A Fatal Crack in the Joint – Reason … weak weld
Moisture problems during electrode storage
Poor welding can prove costly and sometimes even be fatal as heavy machinery, construction, ships, etc., are dependent on the quality of the weld which is in turn dependent on the quality of the coating of the welding electrode.
The flux coating controls and improves the welding process.
The coating of the electrode is made of blends of cellulose, iron powder or low hydrogen and blended with sodium, titania, potassium and iron oxide. The highly hygroscopic coating of the electrodes deteriorates in the presence of moisture during storage.
Common problems of deteriorated coating
- Increased arc voltage
- Spatter loss (liquid metal expelled from welding process. Spatter leaves behind undesirable dots of metal.)
- Under bead cracking (which is not directly visible, and which may result in premature breaking of the joint)
- Poor slag removal
- Porosity in weld deposit
Bry-Air Dehumidifiers: For longer shelf life of electrodes and better-quality weld
Bry-Air Desiccant Dehumidifiers have effectively maintained the exact condition for welding electrode storage at Philips, Alsthom Power, Cochin Shipyard, Indian Oxygen, etc. A relative humidity of 40±5% RH at ambient temperature during manufacture, storage prior to packaging, packaging and bulk user storage is essential for retaining the quality of the mineral coating of the welding electrode.
