The guidelines issued by the USDA state butter can be left out covered & unrefrigerated for a week.
Butter storage life on the counter or in the refrigerator is shortened by light and circulating air. Have you ever noticed when butter is left uncovered it picks up the flavor of food in the refrigerator or odors in the room? The biēm helps in both of those ways by eliminating light exposure and circulating air, once the cap is sealed.
That being said, locations and room temperatures for storage and use vary. We recommend leaving the biem out while in use during the day and storing in the refrigerator overnight or simply storing in the refrigerator when not in use (with the butter still inside the biēm). Storage times can be different depending on the temperature of where you store the biēm but we do not recommend storing in direct sunlight. If you forget to refrigerate overnight, it won't be a problem, but if you store it in a warm place and kept it out for a few weeks, the butter might need to be replaced and the unit cleaned.
Absolutely, they work great! In fact, any food oil will work just fine.
Yes, you can use margarine sticks, but not tubs. (It's not mandatory but, we really want you to switch to butter!)
The biēm is designed to work with butter sticks commonly used across the U.S.! Yes, there are actually two sizes. One is short and stubby and the other is long and skinny, but both sizes are 4 ounces. We thought it was weird too but it happened because of the evolution of butter stick making equipment as it was first developed across the country.
As butter is loaded into the biēm, it travels down from the product’s middle carriage into a reservoir. There, the biēm has layers of ultra-thin heaters that melt the butter. Once melted, butter moves up from the reservoir to spray.
The biēm has a sensor that knows when to turn the heating elements on and off, based on its position. In a nutshell, this sensor tells the biēm when it needs to melt more butter, based on how full-with-butter the biēm’s lower reservoir is. It is normal to see some melted butter in the main chamber where the butter is kept before spraying as a result of residual heat there.
It sprays an estimated .4g of butter per second of spray.
The melt to spray time depends on the initial temperature of the biēm at the time of use. If the biēm has been in use and you are adding more butter, it is quicker than if it was stored in the refrigerator. If you're just starting to use the unit which has been stored on the counter at room temperature, it will take longer than if the unit was just in use. Just "out of the refrigerator" stored start times will also vary depending on temperature of the refrigerator.
The biēm has a patent-pending nozzle design that's designed not to clog. Here’s how it works: It takes the butter it melts through it's reservoir and sends it to the nozzle, where it emerges as a single separate butter stream. Air, not flammable propellants, from another stream, then atomizes it as it meets the butter stream and converts it into a spray.
Most sprays send the product and the propellant, (in many cases propellant that is flammable and will catch fire if used near flames), through the same path. What happens is, any foreign object that gets in that path can be too large and clog the nozzle. We separated that path into two isolated streams where we push butter through one and air (the biēm's propellant) through the other, thus allowing the pathway to remain open when some foreign matter gets in. Conventional old-fashioned "manual pump oil sprays" have this problem and can clog with just a spec of pepper, while the biēm does not.
The biēm is designed with proprietary motion-detecting technology enabling it to detect when it’s picked up and begin warming . No indicator lights will come on during this preheating period, but it is warming in the background. You will still have to turn the biēm on to spray, but the ready to spray time will be reduced once you do. For instance, if the biēm is kept in the refrigerator door it knows when the door is opening and closing, side-to-side, versus being lifted vertically and would begin preheating when it is picked up.
The biēm will turn itself off after a few minutes of non-use or of no movement.
The biēm uses no flammable propellants, just heat and air. Store bought non-stick cooking sprays, like Pam®, use butane or propane in order to spray. They also operate at/under high pressure (often at or near 95 PSI), while the biēm operates at 4.5 PSI. What’s more, the biēm will not burn users because it’s designed to melt butter at a temperature of just 95 degrees. The butter comes out cool because there are microscopic air holes all around the nozzle that cool the spray as it comes out.
It takes approximately 90 minutes to fully charge. The amount of uses before recharge will vary depending where you store it and how many times you use it. A range of the biēm’s usage charge might be anywhere from an estimated week (for a family of four, using it at every meal) to six weeks (for a single person) but this is only an estimate and your results may vary.
The biēm comes with a proprietary, high-density battery pack. There is an LED located at the bottom of the biēm, which turns red as the biēm’s batteries start getting low.
The battery can be recharged at least 500 times or an estimated10 years of normal use charging on average once a week before replacement.
The indicator light on the charger will stay green until a battery is placed in it to charge and will then turn red to indicate charging. Once charging is completed It will change to green. At that time the charger is no longer charging and will stay green indicating the battery is ready for use.
