Give Your Walk-in a Walkthrough

Walk-in coolers and freezers: When is the last time you went into your property’s walk-in cooler unannounced? If you haven’t done it in a while, you might be surprised. I recently had the experience where an excellent GM asked me to identify opportunity areas in the kitchen operation. I went through the walk-in coolers and freezers and found the following issues within the first 10-minute visual inspection:

• 

  Make sure you have an inventory management process in place.

  Walk-in freezer that was very poorly lit (read: hard to find items), with boxes of frozen foods that had not been dated. Clearly without a date, it is hard to employ the First-in, First-out (FIFO) method of inventory management. How do we know when that box of chicken wings on the bottom of the stack came in? It is possible the box on the bottom is living there in perpetuity while new inventory is stacked on top every week?

• Food items stored unwrapped, with no date, in non-translucent storage pans and hotel pans. In one instance, two different products were in the same tray: one was uncooked raw chicken breast stored at an angle so the blood was running into unwrapped Canadian bacon. In a cruel moment of irony, just that morning I had been in the hotel’s restaurant outlet and sat next to four female business travelers who all ordered the eggs benedict for breakfast. When I eventually asked the sous chef (the executive chef was off at the time) what was going on, there was a general lack of awareness and training about the dangers of such poor food handling and the improper storage methods. The acts and non-acts were not malicious; rather it was a training and education issue. Oh, and he thought buying Lexans for storage purposes was too expensive for the GM to approve.
• Soup stored unwrapped in a large container sitting on the floor directly under the cooler’s condenser unit that was dripping water condensation into the soup. Read the rest of this entry »

New Jersey Steak House Goes Above and Beyond on Food Safety

When David Walzog got the go-ahead to design the kitchen for Strip House at The Westminster Hotel in Livingston, N.J., the executive chef’s wish list drew on his experiences working at the Monkey Bar and Michael Jordan’s The Steak House N.Y.C., both in New York City.

Walzog insisted on 14 sets of refrigerated drawers—where food is held below 40F—for mise en place. Several drawers were installed on the line, providing more space for plate assembly and enabling 14 cooks to keep surfaces clean and orderly.

Drawers and gaskets are cleaned daily, and twice a week they’re disassembled for bleaching. The quarry tile floor in the kitchen is graded and easy to hose down and power wash, he says.

Strip House’s five walk-in coolers are extra-spacious. The lowest shelf is 10 inches off the floor, two inches higher than health codes mandate, Walzog says, to facilitate mopping and cleaning. Rubber-coated shelving resists rust and cleans and moves easily to accommodate a variety of bin sizes. Safety glass and wire grating enclose two pairs of fluorescent bulbs for ceiling light.

Proposed Rulemaking for Walk-in Coolers and Freezers

Proposed Rulemaking for Walk-in Coolers and Freezers

Since EISA was passed January 1, 2009, the U.S. Department of Energy (DOE) has been working to mandate a standardized energy efficiency test for walk-in coolers and freezers.  The first step was taken with an informal meeting on February 4, 2009 to discuss comments and suggestions from industry professionals on determining a testing procedure. After nearly a year’s worth of research, DOE has published their proposed testing procedure for walk-in coolers and freezers. A follow-up meeting was scheduled to discuss these proposed rulings, but due to winter weather the meeting was canceled and has not been rescheduled at this time.

In accordance with section 312 of the Energy Independence and Security Act (EISA), DOE published a Notice of Proposed Rulemaking (NOPR) for the test procedure on walk-in coolers and freezers. The NOPR is the first published document for the test procedure rulemaking process for walk-ins. DOE proposes the procedures explained in the NOPR be used to test walk-in equipment. Once performance standards are accepted, manufacturers will be required to use the accepted test to determine compliance and for all representations regarding the energy use of the product.

DOE proposes to adopt a test procedure that contains two separate testing methods; one for the insulated box and the other for the refrigeration equipment. Each of the two components, the insulated box and the refrigeration system, will be tested separately. The manufacturer will be responsible for testing their product respectively and must provide compliance with all testing standards.  Read the rest of this entry »

Types of Refrigeration Systems Used in Walk-ins

Refrigeration systems consist of a condensing unit and an evaporation coil. The condensing unit is located outside the walk-in and the evaporator is located inside the walk-in. The compressor compresses gas to a liquid. The liquid is then pumped through the condensing unit coil while a fan blows outside air through the coil. Gas is condensed to a liquid and is then pumped through a small copper pipe into the walk-in to the evaporator coil. There, through the expansion valve located in the evaporator coil the liquid is allowed to expand back into a gas. The expansion of the liquid to a gas causes a rapid chilling of the evaporator coil. Since heat always flows toward cold, inside the walk-in air is blown across the evaporation coil to let the coil absorb heat from inside the walk-in. The gas is then allowed to exit the walk-in through a larger copper pipe to the condensing unit where it is once again compressed and cooled to a liquid state and returned to the evaporator coil inside the walk-in. There the cycle is started over.

The new EISA law requires all new walk-ins be equipped with high efficiency motors to be compliant. These cost a little bit more but save you money in the long run. Some suppliers may try to sell you non EISA compliant refrigeration systems. To be compliant with the law and purchase the best lifetime value always ask for EISA compliant equipment.

1. Remote Systems - Remote systems are the least expensive systems to purchase. They consist of a condensing unit, evaporator unit and misc. parts such as expansion valve, site glass, dryer, pump down solenoid thermostat, and on freezers a timer and drain heater to install the system. They require the use of a licensed refrigeration installer since they are pumped down and charged with refrigerant gas on site. The installer will also charge for any other parts needed for the install such as copper pipe, pipe insulation, connectors, and electrical. They are less expensive systems to buy with the walk-in but may cost more over all depending on what the going hourly rate is with the installer and the cost of the parts he provides. They also provide an advantage by allowing the condensing unit to be located outside the building. There the condensing unit can dump its heat without adding extra heat to the building and air conditioning systems. Read the rest of this entry »

Walk-in Saves Lives

On Wednesday, August 19th, a tornado ripped through the village of Williamsville, IL leaving parts of the town a disaster with many home’s lost. One particular building that was in the direct path of the storm was a Casey’s General Store. When the storm rolled in, there were 9 employees and customers in the store. The entire front wall of the building was blown out leaving no shelter for the group in the store. Immediately they took cover in the walk-in cooler where they safely remained until the storm ended. After the storm, the only structure of the building still intact and left unharmed was the walk-in combination unit. Check with your local emergency center for the emergency plan that best fits your location.

U.S. Cooler is now leasing walk-ins

Buying a walk-in cooler or freezer is a large expense for any business and not all companies have the cash flow available to purchase a walk-in outright. U.S. Cooler has another option for our customers. Leasing.

By leasing your walk-in, you avoid having to come up with the complete purchase price necessary to buy it outright. Instead, with leasing, the cost is spread out comfortably over a fixed period of time, and only a small initial down payment is required. Leasing removes the need for equity financing. It also allows you to acquire and use an asset without having to make a substantial down payment. Thus, minimizing the affect on your cash flow and working capital.

U.S. Cooler has partnered with Advantage Leasing to provide our customers with a financing program for their walk-in equipment. For more information on the program visit the leasing program page on our website or contact Advantage Leasing for details.
