Magnetic Induction-Powered Evaporation: An Experimental Design

Magnetic induction heating is a highly efficient and novel means of heating food products. This project investigated the potential for using magnetic induction to improve the efficiency of evaporation in the maple industry.

Ask Proctor

Q1: I’m considering switching from a flat pan to a larger pan with continuous flow, and keep hearing about the gradient. What is a gradient and why is it important? Q2: After a warm spell that made the sap stop running, a hard freeze made it start again so I collected and boiled. The syrup had an off-flavor. Why?

How to Choose an Evaporator

When choosing an evaporator, it’s important to find the right size, fuel type, and tools to maximize efficiency.

Energy Efficiency in the Sugarhouse

Boiling syrup is energy intensive, but there are ways for sugarmakers to calcuate and improve their energy use.

Chemical Composition of Scale in Maple Syrup Evaporators

The goal of this work was to investigate the chemical composition of the scale that is deposited on maple evaporator surfaces during sap processing. Knowing the chemical composition of scale produced in modern equipment and how it compares to previously published values for loose sugar sand may aid in understanding how best to remove these unwanted deposits.

Boiling Clean With Air

I have been using the bubbler now for six years. I have found that the bubbler allows me to boil as hard as I want without using any defoamer. Pumping natural clean air into the pans is better than adding defoamer of any kind to make a good tasting and pure product.

Industry Review Air Injection Technology and Its Use in the Production of Maple Syrup

In recent years, some maple equipment manufacturers have sold air injection (AI) technology equipment for the production of maple syrup. For purposes of the recent industry review conducted by the International Maple Syrup Institute, air injection technology is defined as the forced introduction of air through a series of perforated pipes submerged in boiling sap in the front and/or back pan of a maple syrup evaporator.

Technical Position Paper on Air Injection

The use of air injection technology in the maple industry can be defined as: the forced introduction of air through a series of perforated pipes submerged in the boiling sap in the front and /or back pan of a maple syrup evaporator. Several studies conducted in recent years have investigated aspects of the use of air injection technology in the process of maple syrup production.

Vapour Compression Evaporation

The cost of fuel in a typical oil-fired, Open Pan Evaporator (O.P.E.) for a 4000 tap operation can represent 20% of the total syrup production costs. Vapor Compression Evaporation (V.C.E.) offers a method of capturing lost energy and improving the fuel consumption of an O.P.E. Most of the energy goes up in steam and this unit will recapture lost energy to reuse.
