Preserve
flavor
of the past
Although technology is
changing, Ontario maple
syrup producers are preser-
ving the flavor of the past for
today's consumers through
energy -minded ingenuity.
About half of the pro-
vince's producers collect sap
in the traditional manner -
tapping trees by hayed with
spiles and buckets. But
larger and newer producers
use plastic tubing and
vacuum pumps to draw the
sap to a central holding tank.
The plastic tubing not only
reduces the labor required to
collect the sap, it also
reduces the amount of sap
that was spilled en route to
the sugar shack:
The sugar shack has seen
some dramatic changes
since the early settlers hung
their iron kettles over a wood
fire. That kettle could never
handle the quantities of sap
today's producers must pro-
cess to•make maple syrup a
more than $6 million
business. Now, producers
use wood -fired or oil -fired
open pan -evaporators
.capable of handling up to
1,500 litres of sap per hour.
Even . this system isn't
ideal, so producers are look-
ing at alternatives. The cost
of energy to boil the 35 to 40
litres of sap down to one litre
of syrup is pinching the pro-
ducers' pocketbooks.
This season, producers are
expected to spend $1 in
energy costs for, every litre
of syrup they. produce. But
the industry is meeting the
challenge of increasing
energy costs head on by
developing new. technology.
Ontario is becoming' a
leader . in_. ...;research.. and
development of energy-
efficient technology for the
maple syrup industry. Other
maple syrup producing
areas are watching with in-
terest this season as Ontario
producers test three\ new
evaporation processes.
One of the most popular
new developments is the
reverse -osmosis • system.
This process was developed
with assistance of the Na-
tional Research Council. The
Canada -Ontario Con •
-
servation and Renewable
Energy' Program is sponsor-
ing several demonstrations
in Ontario this .. year and
more, than .20 producers
across the ,province are
testing the system this
season.
The reverse -osmosis'
system filters sap through a
semi -permeable membrane.
to obta)n a higher concentra-
tion of sugar in the sap. Tests
indicate that using this
system, 75 per cent of the
water can be removed from
the sap. The theory • behind
the process is that it takes
less energy to convert the
concentrated sap into syrup.
Although the initial outlay
of up to $35,000 for the
system seems high for a
piece of equipment used only
six weeks each year, the
system could pay for itself in
about three years. It is
capable of reducing energy
consumption by up to 65 per
cent.
Another piece of equip-
ment, developed at the
University . of Waterloo, is
the economizer, Research
fdr this unit was funded by
the " Ontario Ministry of
Agriculture and Food and
the "Ontario Maple Syrup
Producers' Association.
The economizer recycles
waste steam from a conven-
tional evaporator to heat the
sap and speed evaporation.
By trapping and using the
waste steam, the economizer
can recapture 94 per cent of
the energy, almost doubling
the efficiency of a conven-
tional evaporator.
Stearn from the
evaporator is ducted into the
economizer and used to heat
the sap to temperatures of
up to 68 C 1155 F, I. Air is
blown over the sap to speed
the evaporation process.
Although the economizer
is not in commercial produc-
tion now, there are several
demonstration models under
test this season. It is ex-
pected that there will be a'
flurry of interest in the
economizer, once people in
the field gain eicperience.
The newest of the energy-
saving technologies is the .
vacuum evaporator. By ap-
plying a strong vacuum over
an enclosed evaporator, the
boiling temperature can be
reduced to as low as 57 C i 135
