Bananas and Food Waste: Grocers Worst Nightmare

What is the worst fruit of all time? Bananas: they’re one of the biggest causes of food waste for grocers. But what does this have to do with temperature control?

Temperature Control and Bananas

food waste

In terms of its ability to waste, Food and Wine magazine rates bananas as the worst. A February 13, 2018 article said bananas are the biggest source of grocery store waste.

Bananas are not the only produce products to rot before it gets to consumers: food is wasted at every step of the supply chain. But bananas stand out because consumers tend to only purchase bananas that they perceive are ripe, which in most cases are a spotless yellow or yellow-green.

Bananas: A Misunderstood Fruit

What consumers don’t understand is that bananas are ripe and edible while green all the way through until black. The darker the banana, the more sweet it is. The lighter the banana, the more starchy it tastes. Bananas can be eaten alone, used in baking, mixed in a smoothie, as a topping for oatmeals and ice cream, and even fried. How they are used is determined by the fruit’s starchy or sweet consistency. As a result, blackened bananas can often be seen as food waste. But even though they’re still useful, bananas that aren’t picturesque are thrown out simply because consumers won’t purchase spotted or blackened bananas. 

Rot in Transit

However, a significant amount of banana waste comes from the transportation of the fruit. Ash Ngu, an expert of banana transportation, described on Quora how the process works.

“Bananas that Americans eat are imported from countries like Costa Rica, Guatemala, Honduras, Mexico and Panama. They’re harvested green and unripened so that they can last the 3-4 weeks it takes to get them into grocery stores. During processing, they’re broken up into bunches, labeled with those little stickers and boxed up in order to protect them during shipping.

“The bananas are transported across the ocean in temperature-controlled ship holds. Once they get to their destination port, a ripening manager inspects the bananas. They’re visually inspected, their temperature is taken, the peel is peeled, banana flesh color and texture is evaluated. Then they go into pressurized rooms which force air through the banana boxes for consistent ripening. The temperature of the room can be controlled to quicken or slow the ripening process. After they are ripened appropriately, the bananas are sent on their final journey in trucks to various grocery shelves across the nation and into your hands.”

Banana Gas

Some producers use chemical gases to speed up the ripening process of bananas. This chemical is called ethylene. A small hydrogen gas, ethylene is a naturally occurring byproduct of ripening fruit, including bananas. Producers will often use ethylene to encourage the ripening of bananas to time their peak “fresh appearance” with the date at which consumers will see them on store shelves.

One conclusion that can be gleaned from learning about the process it takes to get bananas from tree to store is that doing so is very expensive, and that temperature control is critical to helping bananas reach customer at the peak of perfection. There are a few items out there that can help with bringing more fruit to the customer, but refrigeration and ethylene are the main methods used by producers and grocers today. These processes have proven very effective in preventing food waste.

Drum Insulation Blanket

Drum Insulation Blankets
Drum Blanket strapped onto drum with powerblanket logoFrom foods to a variety of chemicals and epoxies or resins, proper storage of your industrial materials is important. Without the right storage conditions, the quality of materials is compromised, leading to lost money on wasted products and ineffective heating methods.

HEATING METHODS

There are a few heating methods for drums and barrels, but some will end up causing you more of a headache. Drums hold a lot of product and offer a durable storage structure for liquids, chemicals, food product, and more. However, when it comes time for temperature regulation, they don’t provide any capabilities on their own. 

Traditional insulation blankets lack the ability to bring your material to working temperature, in addition to inadequately protecting against the savage cold. Take, for example, the need to bring certain types of product to temperatures above the ambient air around it. A typical insulation blanket has no way to accommodate this. 

While cartridge heaters are also an option, they can be a lot more work. Cartridge heaters heat a small area, require precise tolerances for drilled holes and need additional exterior insulation. They are used most often for molds or metal parts and inserted into drilled holes. Heating from the inside works well for some applications, but uneven heat is a common issue for cartridge heaters.

With a thermostatic controller and innovative heat-spreading technology, you can wrap your drum and forget about it.

THE POWERBLANKET DIFFERENCE

Of all the heating devices out there for the protection of drums and barrels, this drum blanket is one that’s done right. With even heat distribution and temperature regulation, Powerblanket has a solution fit for any occasion. 

Freeze Protection

Wrap anything in a Powerblanket drum heater and you’ll never use another band heater or blower again. Powerblanket heated drum blankets takes the hassle out of heating your barrels & totes with an insulated barrier of warmth from top to bottom. They offer a full-wrap, insulated design for superior control and freeze protection. This ensures that there is even heat distribution, preventing hot and cold spots that could be damaging to your material. You also have multiple sizes & temperature settings to choose from.

Improve Viscosity and Flow

Storing material in freezing weather can result in higher viscosity, while hot spots creates lower viscosity, resulting in increased flow. Improper storage and heating methods can be especially problematic for temperature-sensitive material. If it becomes too hot or cold, it be very time-consuming to achieve required viscosity again, and may completely ruin certain materials. Viscosity issues can cause a multitude of problems with productivity and money.

The ability to automate your freeze protection is a huge benefit once the cold weather rolls around, and the capability of bringing liquids and other products to higher temperatures for viscosity maintenance, chemical-property enablement, or characteristic integrity is of equal importance. Heating sensitive materials has never been easier with drum blankets, available in fixed temperature or adjustable control.

Need Custom Heating for Your Equipment? Answer These Questions

Do you need custom heating for a specific and unique application? Although there are various standardized heating solutions available, to determine the right solution, either standard or custom, a few initial questions need to be understood. The first of the discovery questions is to identify the desired result of the application which is generally one or a combination of the following:Custom Heating

  1. Freeze Protection:  Generally to protect from the elements or cold climate
  2. Temperature Maintenance:  Maintain a specific, constant and optimal temperature
  3. Added heat or Increase Temperature:  Add heat  and Increase temperature higher from starting point

For example, a pipe heating application may require higher energy/wattage to thaw a frozen pipe and then settle to a moderate power/wattage for continual freeze protection and flow control long term.

An epoxy/composite curing application may require pre-heating at higher temperatures prior to the epoxy being applied and then maintained at a higher temperature for optimal curing.

Begin with These Steps

  • Gather as much information as possible using the Custom Application Questionnaire. Be thorough.
  • The dimension needs to be as built, not a CAD drawing .  ALL dimensions must be submitted to the custom team for quote.
  • Once quote is accepted and PO is sent, engineering will begin.
  • Custom products will normally be completed within two weeks.

Custom Application Questionnaire

Once we understand the problem, these types of questions reveal the best solution:

  1. Which of these best describes the system requiring Cooling: drum/bucket, tote, tank, gas cylinder, pipe, flat surface (vertical or horizontal?), other?  
  2. Can you provide drawings and/or photos?  
  3. What are the critical dimensions of the system?  
  4. What material is the container or surface made of (i.e. tank wall, drum wall)? How thick? 
  5. What is the substance being Cooled (i.e. water, oil, pipe contents, concrete, frozen ground)? 
  6. Is this a flowing system? If so, what is the flow rate (include units, gpm, cfm, etc.)? 
  7. What is the expected ambient temperature (include units, °F, °C)? 
  8. What is the maximum expected wind velocity (include units, mpg, km/h, etc.)? 
  9. Are there other environmental conditions that may be relevant? 
  10. What is the beginning temperature of the substance or contents (include units, °F, °C)? 
  11. What is the desired final temperature of the substance or contents (include units, °F, °C)? 
  12. What temperature range is acceptable? 
  13. Are there upper or lower temperatures where the substance or contents will be damaged? 
  14. Is there a time frame requirement for the initial cool down? 
  15. What power source is preferred (120, 208, 240, DC)?  
  16. How far away is the power source (cord length)? 
  17. Do you require UL/CSA certified products? 
  18. Is your location considered hazardous (Class I Division 2)?
  19. How many units do you need now and in the future? 
  20. What is the required delivery date? 

Custom Heating Case Study

Powerblanket completed a project for a large chemical company to solve freeze protection problems. The company stores a chemical solution in large 4,000 to 8,000 gallon stainless steel tanks. Their customers live in various climates throughout North America. This solution is water based and freezes at roughly 32°F.  This company needed freeze protection and to maintain regular temperatures between 40°F -70°F.

The question became, “How do we provide a ‘one size fit all’ customized solution for various climates?” Powerblanket created a modular custom design, adjustable by region and tank size, that came in two pieces.

Powerblanket engineers calculated the amount of heat and insulation required to combat freezing temperatures and wind chill to maintain optimal temperatures in these various climates. What appeared to be a complicated application turned into a simple and effective custom solution.

So many industries need heating solutions, and not just during the cold months either. Epoxy curing, chemical storage, viscosity maintenance, food preparations, concrete curing, and much more all benefit from innovative temperature regulation year round.
