Configuration issue on heroku with rabbitMQ (cloudamqp addon) - ruby application

Question

First of all this is working fine in my local machine.

I have one publisher app (Rails 3), which is publishing message to cloudamq(addon) in heroku, we are getting messages in cloudamq

and one consumer application (Rails 5) which is also running on heroku as a separate app, i put this consumer in a rake task but here the issue is this takes messages from the queue only when we restart the server, that means this rake task will run when we restart, but in rabbitMQ it shows always running

So how can we make the consumer to listen continuously once we push to heroku?

Also once we get the message from queue i have to call a sidekiq worker, that is not happening? using 'redis to go' addon

CONSUMER APP

Gem which i have used in this cosumer application

gem 'redis', '~> 3.0'

gem 'sidekiq'

gem 'bunny'

This is the consumer part to get the message from queue as a rake task.

 task :do_consumer => :environment do

   connection = Bunny.new(ENV['CLOUDAMQP_URL'])

   connection.start # start a communication session with the amqp server

   channel = connection.channel()

   queue = channel.queue('order-queue', durable: true)

   puts ' [*] Waiting for messages. To exit press CTRL+C'

   queue.subscribe(manual_ack: true, block: true) do |delivery_info, 
   properties, payload|
      puts " [x] Received #{payload}"
      puts " [x] Done"

      channel.ack(delivery_info.delivery_tag, false)
      # Call sidekiq worker to do task
      callSidekiqWorker.perform_async(payload)
   end
end

Procfile

web: bundle exec puma -C config/puma.rb
worker: bundle exec sidekiq -e production
worker: bundle exec rake do_consumer
